Abstract
The controller includes motor control means for controlling the drive RPM of a motor generator to reach a specified RPM less than the idle RPM when the braking condition of a foot brake is detected by a brake-operating-state detecting means while a motor generator is being rotated at an idle RPM or more. This reduces uncomfortable shock which tends to occur because of a change in the rotation of the motor during braking as much as possible to improve drive feeling.
Claims20
A control device, for a hybrid vehicle having a motor including a rotor and a stator capable of transmitting the driving forces of an engine and the motor to downstream power transmission components comprising:
- brake-operating-state detecting means for detecting the operating state of a brake for braking or releasing the driving wheel;
- and
- motor control means capable of controlling the rotational speed of the motor to a predetermined rotational speed less than an idling rotational speed when the brake-operating-state detecting means detects the braking state while the motor is being rotated at an idling rotational speed or more with the engine ignition off.
A control device, for a hybrid vehicle having a motor including a rotor and a starter capable of transmitting the driving forces of an engine and the motor to the downstream of power transmission and rotating the rotor with a driving wheel in the downstream of power transmission braked, comprising:
- a brake-operating-state detector that detects the operating state of a brake for braking or releasing the driving wheel;
- and
- a motor controller capable of controlling the rotational speed of the motor to a predetermined rotational speed less than the idling rotational speed when the brake-operating-state detecting means detects the braking state while the motor is being rotated at an idling rotational speed or more with the engine ignition off.
