ELECTRONIC SHIFT LEVER SYSTEM GENERAL


  1. OUTLINE


    1. The electronic shift lever system is a shift control system using a shift-by-wire technology.

    2. This system judges the vehicle conditions based on the information from various sensors, switches and ECUs and activates appropriate shift control in accordance with the driver's shift lever and P position switch operations.

    3. A compact shift lever is used. It is a momentary shift type that returns to the home position when the driver's hand is released from the shift lever after a shifting operation. It can be shifted with a fingertip, and the ergonomically designed shifting pattern offers excellent ease of operation.

    4. A shift lever position sensor provided in the shift lock control unit assembly detects the shift position (R, N, D or B) and sends a corresponding signal to the power management control ECU (HV CPU). The power management control ECU (HV CPU) controls the speed of the engine, Motor Generator 1 (MG1) and Motor Generator 2 (MG2), in order to produce an optimal gear ratio.

    5. With this system, when the driver presses the P position switch, the P position control actuates the parking lock actuator located in the transaxle in order to mechanically lock the parking gear, which engages the parking lock.
