    摘要: An automatic engine-stop control apparatus for a vehicle includes a vehicle speed sensor and a brake pedal depression sensor which are coupled to a control unit. The control unit is programmed to decide that the vehicle speed detected by the vehicle speed sensor is smaller than or equal to a predetermined stop expected speed when the brake pedal depression sensor detects that the brake pedal is depressed, and to decide that the vehicle is stopped when a predetermined time period elapses from a moment that the vehicle speed becomes smaller than or equal to the predetermined stop expected speed and when the depression of the brake pedal is continued.

    摘要: An engine start control apparatus includes a motor/generator and a controller for controlling the motor/generator. The controller starts an engine cranking operation to start the engine by operating the motor/generator in a cranking mode for driving an engine in response to an engine start command signal, monitors an operating condition of the engine cranking operation to produce a mode change signal before an engine speed exceeds a target speed, and switches the motor/generator from the cranking mode to an overshoot control mode to control the power generation of the motor/generator in accordance with a predetermined target parameter such as a target power generation torque and a desired engine speed.

    摘要: In a hybrid vehicle wherein the rotation torques of a motor and engine are input to a continuously variable transmission, a drive force is controlled by a microprocessor programmed to set a target drive power (tPO) based on a depression amount of an accelerator pedal (APO) and a vehicle speed (VSP), set a battery power (PB) based on a battery charge amount (SOC), set a target engine power (tPE) based on the target drive power (tPO) and the battery power (PB). The microprocessor is also programmed to set a limited target engine power (tPELMT) to zero when the target engine power (tPE) is less than a predetermined value, and set the limited target engine power (tPELMT) equal to the target engine power (tPE) when the target engine power (tPE) is larger than the predetermined value. The microprocessor is further programmed to set a target engine torque (tTE) and a target engine rotation speed (tNE) based on the limited target engine power (tPELMT), set the target motor/generator torque (tTMG) based on a target motor/generator power (tPMG) and the input rotation speed (NI), and set the target speed ratio (tRVO) based on the target engine rotation speed (NI) and the vehicle speed (VSP).

    摘要: When engine operation falls in a predetermined zone wherein it is necessary to attenuate engine surging or the like type of engine operating phenomenon, and wherein mapped adaptive update value data is required to exhibit a different resolution to the adaptive update value data which is contained in the remainder of the map not included in the predetermined zone, the operation of the engine in the predetermined zone is detected and an indication of the same set. While the indication is set, updating of the mapped data which corresponds to the predetermined operational zone, is inhibited. In some embodiments mapped data which corresponds to the predetermined operational zone is set in a separate memory section and updated in a manner different from the manner in which the data which does not correspond to the special zone, is updated.
