СИСТЕМА МЕХАНИЧЕСКОЙ ТРАНСМИССИИ


  1. FUNCTION


    1. In Gear Shift Indicator system, the ECM calculates an environmentally favorable shift position based on the vehicle conditions, and makes a request to the meter ECU to indicate upshifting or downshifting. Then, Gear Shift Indicator in the combination meter gives a shifting recommendation to the driver.

    2. The ECM determines the actual gear position based on the signals from the crank position sensor and speed sensors, and the target gear position based on the signals from the accelerator pedal position sensor and speed sensors.

    3. By driving in accordance with the shift change recommendations indicated by Gear Shift Indicator, the driver can enhance environmental performance, improve fuel economy and reduce exhaust gas output within the limits of engine performance.

      Control of Gear Shift Indicator System
      Control Outline
      System Start Checks the bulb of the indicator lights from the time the ignition switch is turned to ON until the engine is started.
      Shifting Recommendation Control Calculates an environmentally favorable shift position based on the driving conditions of the vehicle, and gives a shifting recommendation.
      Shift Control in Uphill Traveling Prevents unnecessary shifting instructions by estimating the gradient of the road based on the driving conditions, and provides shift position instructions that enable the vehicle to attain the proper drive force.
      Delta Throttle Acceleration Control Detects a deceleration request when the driver releases the accelerator pedal suddenly. Thus, this control will not provide an upshift instruction. However, it will provide an upshift recommendation to protect the engine if the engine speed is high.

    4. Gear Shift Indicator system will not perform control while the vehicle is being driven in reverse.

    5. Gear Shift Indicator system will not perform control while the vehicle is stopped or the clutch is not engaged while shifting.

    6. Upon receiving a shift instruction request from the ECM, the meter ECU will illuminate the indicator light.

    7. The 2 indicator lights illuminate simultaneously during a bulb check.
