Description

An optimal seat position set by a driver can be memorized in P/seat unit by memory SW and position SW, which enables restoration of seat position set by the driver despite seat adjustments.

Furthermore, data is transmitted between P/seat and IPM, DDM, ADM, RAM, FAM, CLUSTER through CAN BUS.

Seat position presets cannot be recalled while driving. An emergency stop function is provided; additional functions are described below.

  1. It conducts manual operation of seat by CAN BUS data transmitted by DDM as well as that of adjustable pedal by CAN BUS data transmitted by IPM received when operating SW manually.
  2. Manual SW behavior when communication stops (back-up behavior) Slide front/rear Recline front/rear Position control of slide motor is possible by manual SW even in case of congestion in CPU or removal of a fuse for P/seat unit B.
  3. 2 memory locations are provided for storing seat, outside mirror, and adjustable pedal presets.
  4. The driver seat can be set to slide rearward when the ignition key is removed, and forward when the key is inserted.
  5. 2 additional presets for seat, mirror, and adjustable pedal position can be stored with the RKE transmitter.

Manual Operation

Manual operation of the driver seat and adjustable pedals is possible provided the transaxle is in 'P' range and the vehicle speed is 0 MPH. Operation of the manual controls overrides any automatic operation commanded via CAN.

Memory Operation

  1. Pressing the 'M' button on the control panel will place the system into memory storage mode and will result in a single pulse from the output buzzer.
  2. If one of the memory location buttons is pressed and held within 5 seconds of pressing the 'M' button, the output buzzer will pulse twice to indicate successful storage of seat, mirror, and adjustable pedal positions.
  3. The ignition switch must be in the RUN or START position, the vehicle speed must be 0 MPH, and the transaxle must be in 'P' range to store memory presets.
  4. Pressing the 'M' button while recalling a stored preset will halt the preset recall operation.
  5. Memory will be cleared if battery is removed.

Memory Replay Operation

  1. Pressing one of the memory location buttons will result in the driver seat, outside mirrors, and adjustable pedals being positioned based on the stored preset data.
  2. The ignition switch must be in the RUN position, the transaxle must be in 'P' range, the vehicle speed must be 0 MPH, and the manual functions must not be in operation to recall stored presets.
  3. Others Play operation not recorded in the position switch will not be conducted and there will be no buzzer output. If other data is received during preset recall operation, the most recent preset recall signal will take precedence. If engine is started during preset recall operation, halt preset recall operation, and resume it toward target position 100ms after Ignition switch is returned to "RUN". However, if the START state lasts over 5 sec., it will not resume even after returning to RUN. If preset recall order is received during engine start, preset recall operation is inhibited. If input from manual switch for seat and adjust pedal occurs during preset recall operation of seat and adjust pedal, halt all their preset recall operations. If an error occurs during manual operation of seat and adjust pedal, delete Memory.
  4. Operation control

  1. Prioritization of operations Motor starting is delayed for 100ms respectively in case of auto control to prevent rush current from overlap when motors are running, and it follows the following order. Slide > recline > front height > rear height > adjust pedal.
  2. Memory preset recall is conducted in the following order, and delay time for each motor is as follows. T1 : Maximum 0.1 sec. Continuous cooperation TIMER value for each motor. Slide: 15 sec., recline: 30 sec., front height: 5 sec., rear height: 8 sec., adjust pedal: 10 sec.
  3. Control when turning to the opposite direction. When motor has to be run in a reverse direction during Easy access function or preset recall operation, stop the operation immediately, wait for 100ms and then try operation to the reverse direction.
  4. If the difference between position and the current one is below specified value, motor will not run even though preset recall data is received. Slide, recline, front height, rear height : 6 PULSE Adjust pedal: 3LSB (about 0.06V)
  5. Operation will stop upon reaching Motor's target point when conducting Easy access function or preset recall operation.

Easy Access Function Operation (Slide Motor Only)

  1. Easy access function operation is allowed only when auto switch is on, and the operation will be halted if auto switch changes from on to off.
  2. If a key is removed and CAN BUS data transmitted from IPM changes from "on" to "off", the seat slide will move 50 mm backward based on the IGN off point. If a key off position is farther back than 50 mm against the IGN off point, get-off gearing will not be conducted. If slide rear limit becomes off in the middle of backward operation, retreat control will be halted.
  3. The following conditions will be identified and processed by IMS, and if any one of the following conditions is met, Easy access function operation will be prevented or halted. When "P" position switch is not on. When Vehicle Speed in CAN BUS data transmitted from cluster is "3 km/h" or faster. When seat and pedal is under manual switch operation. When auto switch is off.
  4. When control is halted in the middle of backward operation, the remaining operation will not be completed, and when returning, it will return just as much as it retreated.
  5. It will move to IGN off point in case of Get-on gearing by key in despite manual switch input during or after backward operation.
  6. After the key is removed, on the condition of SLEEP state, Easy access function operation will be conducted after 150 ms if the key is inserted when auto switch is turned ON (OFF) from OFF (ON).

Memory Storage Operation By Keyless

  1. If "ID1" or "ID2" is received during keyless lock operation, record seat and pedal position in keyless code. (There is no buzzer output during memory storage operation by keyless)
  2. Memory storage operation is allowed for a single ID after a change of IG from "on" -->"off".
  3. Any one of the following conditions will prevent keyless Memory storage operation.
  1. When "P" position switch is not on.
  2. When Vehicle Speed in CAN BUS data transmitted from CLUSTER is "3 km/h" or faster.
  3. When seat and pedal is manipulated by CAN BUS and manual switch.
  4. When IG transmitted from IPM is other than off.

Preset Recall Operation By Keyless

  1. When IG is off (CAN BUS data IG transmitted from IPM is "off") and a key is removed (CAN BUS data Key Reminder Switch transmitted from IPM is "off"), and if "ID1" or "ID2" is received during keyless unlock operation, it automatically adjusts seat and pedal positions as memorized in keyless code (there is no buzzer output during preset recall operation by keyless). However, seat slide adjustment position is determined as follows, depending on Auto switch. When auto switch is on ("IMS Auto Switch" is "on"), the position is automatically adjusted to 50 mm farther back than target position, and if a key is inserted ("Key Reminder Switch" changes from "off" to "on"), it conducts Get-on gearing operation to a target preset recall position. If auto switch is off ("IMS Auto Switch" is "off"), it moves to the target memory play position.
  2. Any one of the following conditions will prevent preset recall operation. When "P" position switch is not on. When Vehicle Speed in CAN BUS data transmitted from cluster is "3 km/h" or faster. When seat and pedal is manipulated by CAN BUS and manual switch. When IG Switch transmitted from IPM is other than off. When a key is inserted.
  3. Playing will be halted during preset recall operation if any of the following conditions is met.
  1. When "P" position switch is not on.
  2. When vehicle speed in CAN BUS data transmitted from cluster is "3 km/h" or faster.
  3. When seat and pedal is manipulated by CAN BUS and manual switch.
