Abstract
In the vehicle control system, a controller may perform first regenerative control that causes a motor generator to perform regeneration so as to apply a braking force to a vehicle when the accelerator is off and, when the accelerator is off and a steering is turned, perform second regenerative control that causes the motor generator to perform regeneration so as to apply a braking force to the vehicle in order to control the vehicle attitude by generating a deceleration that corresponds to a steering angle in the vehicle in addition to the first regenerative control.
Claims13
A vehicle control system, comprising:
- a generator configured to perform power regeneration by being driven by a wheel of a vehicle;
- a steering wheel configured to be operated by a driver;
- a steering angle sensor configured to detect a steering angle corresponding to an operation of the steering wheel;
- and
- a controller configured to perform first regenerative control that causes the generator to perform power regeneration so as to apply a braking force to the vehicle when an accelerator pedal of the vehicle is in an off state and perform second regenerative control that causes the generator to perform power regeneration so as to apply another braking force to the vehicle in order to control a vehicle attitude by generating, in the vehicle, a deceleration that corresponds to the steering angle detected by the steering angle sensor in addition to the first regenerative control when the accelerator pedal of the vehicle is in the off state and the steering wheel is turned,
- wherein the controller is configured to operate an anti-lock brake system so as to suppress a locked state of the wheel when a predetermined wheel state value indicating the locked state of the wheel is equal to or more than a first threshold, and
- the controller is configured to reduce a first regenerative amount of power applied in the first regenerative control and/or a second regenerative amount of power applied in the second regenerative control under a condition the wheel state value is equal to or more than a second threshold that is less than the first threshold when the accelerator pedal is in the off state and the steering wheel is turned.
