Abstract
A brake control device includes a deciding unit for deciding a requested deceleration that is requested by the driver, based on the brake pedal operation amount that is acquired, and a braking processing unit for deciding a braking amount of braking to be executed by a brake device, based on the requested deceleration that is decided, and deciding to execute reducing control in which a deceleration is reduced as compared to the requested deceleration immediately before stopping a vehicle. The braking processing unit is configured to execute increasing control in which a deceleration is increased as compared to the requested deceleration before executing the reducing control, and decides whether to execute the increasing control based on the detection result of the in-vehicle sensor.
Claims2
A brake control device comprising:
- an acquisition unit that acquires a brake pedal operation amount of a brake pedal operation performed by a driver, and a detection result of an in-vehicle sensor;
- a deciding unit for deciding a requested deceleration that is requested by the driver, based on the brake pedal operation amount that is acquired;
- and
- a braking processing unit for deciding a braking amount of braking to be executed by a brake device, based on the requested deceleration that is decided, and deciding to execute reducing control in which a deceleration is reduced as compared to the requested deceleration immediately before stopping a vehicle, wherein
- the braking processing unit is configured to
- execute increasing control in which the deceleration is increased as compared to the requested deceleration before executing the reducing control,
- decide whether to execute the increasing control based on the detection result of the in-vehicle sensor, the detection result of the in-vehicle sensor including information regarding an object for stopping, located in a traveling direction of the vehicle,
- decide to execute the increasing control when detection is made that the object for stopping is present in the traveling direction of the vehicle, and
- decide not to execute the increasing control when detection is not made that the object for stopping is present in the traveling direction of the vehicle.
A brake control device comprising:
- an acquisition unit that acquires a brake pedal operation amount that is the amount of operation of a brake pedal performed by a driver, and a detection result of an in-vehicle sensor;
- a deciding unit for deciding a requested deceleration that is requested by the driver, based on the brake pedal operation amount that is acquired;
- a braking processing unit for deciding a braking amount of braking to be executed by a brake device, based on the requested deceleration that is decided, and deciding to execute reducing control in which a deceleration is reduced as compared to the requested deceleration immediately before stopping a vehicle;
- and
- an estimating unit that estimates an estimated requested deceleration that is a deceleration requested later than an initial stage of depression, based on the brake pedal operation amount at an initial stage of depression in which the driver starts depressing the brake pedal, and calculates an increased requested deceleration in which the estimated requested deceleration is increased, wherein,
- the braking processing unit is configured to
- execute increasing control in which the deceleration is increased as compared to the requested deceleration before executing the reducing control,
- decide whether to execute the increasing control based on the detection result of the in-vehicle sensor,
- decide to execute the increasing control for controlling the brake device in accordance with the increased requested deceleration when a difference between the increased requested deceleration and the requested deceleration is within a predetermined range, and
- decide not to execute the increasing control when the difference between the increased requested deceleration and the requested deceleration is outside of the predetermined range.
