        *3: Regarding Battery Integrated Current

        In the stop and start system, the engine stop and start ECU switches the system control mode (stop and start system control permitted/prohibited) based on the battery condition (charge/discharge condition) to protect the battery and to ensure stable engine restarting performance.

        The battery charge-discharge condition is determined from the integrated current value calculated from the battery current sensor signal. The integrated current value is obtained by multiplying the current (ampere) detected from the battery current sensor assembly by the time (seconds), and it is expressed in the unit A-sec. This can be measured by Global TechStream (GTS).

        The engine stop and start ECU determines the power charge based on the integrated current value, and it prohibits stop and start system control if the value is below the threshold, because the battery might not be able to start the engine. The threshold values according to the battery temperature and battery charge condition.

        *3: Regarding Battery Integrated Current

        In the stop and start system, the engine stop and start ECU switches the system control mode (stop and start system control permitted/prohibited) based on the battery condition (charge/discharge condition) to protect the battery and to ensure stable engine restarting performance.

        The battery charge-discharge condition is determined from the integrated current value calculated from the battery current sensor signal.

        *2: Models with CVT

        *3: The engine does not start with the N or P position even though the brake pedal is released.

        *4: Models with M/T

  4. SYSTEM CONTROL


    1. Early Stage Injection Control


      1. Early stage injection control shortens the time it takes the engine to restart after the stop and start system stops the engine, thus allowing smooth initial acceleration.

      2. The ECM memorizes the crankshaft angle detected by the crank position sensor when the engine is stopped by the stop and start system.

      3. The ECM judges the injection required and decides which cylinder to ignite when the driver does restart operation. The ECM then uses this information as it starts the engine.

        A005G58E09

    2. Stopping Position Control*


      1. While the engine stopping operation is performed, the ECM uses ignition timing and alternator load torque to control the crankshaft position so that it is at the optimal position for engine start.

      2. The ECM calculates the amount of electricity that needs to be generated to produce the load torque necessary for controlling and sends requests for electricity generation to the alternator via the stop and start ECU. The ECM inputs the applied crankshaft angle signal and performs feedback.

    3. Hill-start Assist Function


      1. The driving force (creep phenomenon) of a former CVT vehicle is regulated by depressing the brake pedal while stopping, and the driving force is transmitted by releasing the brake pedal when starting the vehicle. However, when starting a stop and start system equipped vehicle with its engine stopped due to the activation of the idle stop function, there is a short time delay of the driving force to be generated as the engine will start after the brake pedal is released.

      2. The hill-start assist function is a system to assist starting of a stop and start system equipped vehicle on a slope to deal with the reason described above, retaining the brake hydraulic pressure until the driving force is generated, and releasing the brake hydraulic pressure automatically after the driving force is generated.

    4. Tandem Solenoid Starter Control*


      1. Tandem solenoid starter (starter assembly) equips with a pinion push out solenoid (SL1) and a motor drive solenoid (SL2) separately so that the pinion can engage with the ring gear even if the engine is rotating by its inertia before fully stopping.

      2. If there is an engine start request while the engine is rotating by its inertia before fully stopping, the engine stop and start ECU drives the pinion push out solenoid (SL1) by determining the timing to push out the pinion to engage with the ring gear in accordance with the state of reduction of the engine rotation. After the pinion and the ring gear engages and a certain period of time passes, the motor drive solenoid (SL2) is driven to crank the engine.

      3. ICR (Inrush Current Reduction) has been provided for the purpose to stabilize the vehicle's power supply voltage by suppressing a large current (rush current) to be flew temporarily at the time when initiating the starter motor.

        Tech Tips

        *1: Even if the engine food is opened while the idling stop control is active, the engine starts if the shift lever is in the P or N position. However, the engine does not start if the shift lever is in the D position. In this case, start the engine with the normal starting operation after moving the shift lever in the P or N position.

        *2: Regarding Battery Integrated Current

        In the stop and start system, the engine stop and start ECU switches the system control mode (stop and start system control permitted/prohibited) based on the battery condition (charge/discharge condition) to protect the battery and to ensure stable engine restarting performance.

        The battery charge-discharge condition is determined from the integrated current value calculated from the battery current sensor signal. The integrated current value is obtained by multiplying the current (ampere) detected from the battery current sensor assembly by the time (seconds), and it is expressed in the unit A-sec. This can be measured by Global TechStream (GTS).

        The engine stop and start ECU determines the power charge based on the integrated current value, and it prohibits stop and start system control if the value is below the threshold, because the battery might not be able to start the engine. The threshold values according to the battery temperature and battery charge condition.

        *3: If the ECM has been replaced or the ECM's learning value is cleared by using a diagnosis tool, the stop and start system operation will be prohibited after the ECM's ISC flow rate learning is completed.

    1. Backup Boost Converter


      1. The backup boost converter uses a semiconductor relay. The semiconductor relay also functions as a fuse. When overcurrent is detected, the relay is turned off to protect the circuit.

      2. The backup boost converter supplies battery voltage to help make up for the voltage drop that occurs when the engine is restarted. This prevents the operation of the following equipment from being interrupted due to low battery voltage.

    2. Permanently Engaged Gear Mechanism*


      1. In this permanently engaged gear mechanism, the bearing, one-way clutch, and ring gear are positioned between the crankshaft and the flywheel or drive plate and ring gear sub-assembly, allowing the pinion gear of the starter and the ring gear to be continuously engaged.

        *9 Drive Plate and Ring Gear Sub-assembly - -

      2. When the engine is being started or restarted, the starter starts operating and the ring gear sub-assembly rotates. Then, the inner race of the ring gear sub-assembly pushes the sprags against the outer race, locking the ring gear sub-assembly to the crankshaft, thus turning the crankshaft and starting the engine.

  7. DIAGNOSIS


    1. When the engine stop and start ECU detects a malfunction and CAN communication is normal, the engine stop and start ECU records information related to the fault. Furthermore, the stop and start cancel indicator light in the combination meter assembly blinks to inform the driver that all CAN communication are normal.

    2. The engine stop and start ECU will also store the Diagnostic Trouble Code (DTC) of the malfunctions. The DTC can be read using the Global TechStream (GTS).
