Braking control device
The braking control device includes a determination unit configured to determine whether a vehicle is in a stopped state; a setting unit configured to set a vehicle stop maintenance braking force necessary for maintaining the stopped state of the vehicle; and a control unit configured to execute, when the determination unit determines that the vehicle is in the stopped state and an actual braking force applied in the stopped state of the vehicle is greater than the vehicle stop maintenance braking force set by the setting unit, vehicle stop maintenance control for decreasing the actual braking force toward the vehicle stop maintenance braking force regardless of a required braking force required by at least one of a driver of the vehicle and another device.
1. A braking control device comprising:
a determination unit configured to determine whether a vehicle is in a stopped state;
a setting unit configured to set a vehicle stop maintenance braking force necessary for maintaining the stopped state of the vehicle; and
a control unit configured to execute, when the determination unit determines that the vehicle is in the stopped state and an actual braking force applied in the stopped state of the vehicle is greater than the vehicle stop maintenance braking force set by the setting unit, and while a required braking force required by at least one of a driver of the vehicle and another device is increasing, vehicle stop maintenance control for decreasing the actual braking force toward the vehicle stop maintenance braking force regardless of a required braking force required by at least one of a driver of the vehicle and another device.
2. The braking control device according to claim 1 , wherein in the vehicle stop maintenance control, the control unit gradually decreases the actual braking force to the vehicle stop maintenance braking force.
3. The braking control device according to claim 2 , wherein in the vehicle stop maintenance control, the setting unit increases the vehicle stop maintenance braking force toward the required braking force when a difference between the required braking force and the vehicle stop maintenance braking force is equal to or larger than a predetermined value.
4. The braking control device according to claim 3 , wherein in the vehicle stop maintenance control, when increasing the vehicle stop maintenance braking force with an increase of the required braking force, the setting unit increases the vehicle stop maintenance braking force at an increasing speed smaller than an increasing speed of the required braking force.
5. The braking control device according to claim 4 , wherein the control unit ends the vehicle stop maintenance control when a probability of starting up the vehicle is high.
6. The braking control device according to claim 3 , wherein the control unit ends the vehicle stop maintenance control when a probability of starting up the vehicle is high.
7. The braking control device according to claim 2 , wherein the control unit ends the vehicle stop maintenance control when a probability of starting up the vehicle is high.
8. The braking control device according to claim 1 , wherein in the vehicle stop maintenance control, the setting unit increases the vehicle stop maintenance braking force toward the required braking force when a difference between the required braking force and the vehicle stop maintenance braking force is equal to or larger than a predetermined value.
9. The braking control device according to claim 8 , wherein the control unit ends the vehicle stop maintenance control when a probability of starting up the vehicle is high.
10. The braking control device according to claim 8 , wherein in the vehicle stop maintenance control, when increasing the vehicle stop maintenance braking force with an increase of the required braking force, the setting unit increases the vehicle stop maintenance braking force at an increasing speed smaller than an increasing speed of the required braking force.
11. The braking control device according to claim 10 , wherein the control unit ends the vehicle stop maintenance control when a probability of starting up the vehicle is high.
12. The braking control device according to claim 1 , wherein the control unit ends the vehicle stop maintenance control when a probability of starting up the vehicle is high.
