Abstract

Provided is a vehicle control device 1 for supporting deceleration in order to stop a vehicle at a predetermined stop location, the vehicle control device 1 including energy regeneration amount computation means 11 for computing an energy regeneration amount caused by deceleration, and operational timing determination means 12 for determining an operational timing in the deceleration based on the energy regeneration amount. It is possible to realize traveling of the vehicle with excellent fuel consumption without degrading the overall energy regeneration amount when the vehicle stops.

Claims (18)

1. A vehicle control device for supporting deceleration to stop a vehicle at a predetermined stop location, comprising:

energy regeneration amount computation means for computing an energy regeneration amount by the deceleration; and

operational timing determination means for determining an operational timing of the deceleration based on the energy regeneration amount,

wherein the operational timing determination means determines the operational timing in the deceleration so as not to be delayed in comparison with a predetermined operational timing obtained from a distance from the vehicle to the stop location, a vehicle velocity, and a deceleration velocity,

wherein the deceleration velocity is constant at the timing of the predetermined operation, and

wherein the operational timing determination means determines an operational timing in the deceleration in a region where regeneration efficiency relating to the energy regeneration amount is higher than regeneration efficiency in the travel pattern where the vehicle travels at the constant deceleration velocity.

2. The vehicle control device according to claim 1 , wherein an operation of the deceleration includes acceleration-off and brake-on subsequent to the acceleration-off.

3. The vehicle control device according to claim 2 , wherein the deceleration velocity of the vehicle is reduced so as not to delay the acceleration-off in comparison with the predetermined operational timing.

4. The vehicle control device according to claim 2 , wherein a braking control is performed at the time of the brake-on.

5. The vehicle control device according to claim 1 , further comprising operational timing notification means for notifying a driver of the vehicle of the operational timing based on the energy regeneration amount.

6. The vehicle control device according to claim 1 , wherein the energy regeneration amount is computed by considering past operational timing of the driver.

7. The vehicle control device according to claim 1 , further comprising:

operation control means for controlling the operation.

8. A vehicle control device for supporting deceleration to stop a vehicle at a predetermined stop location, comprising:

energy regeneration amount computation means for computing an energy regeneration amount by the deceleration; and

operational timing determination means for determining an operational timing of the deceleration based on the energy regeneration amount,

wherein an operation of the deceleration includes acceleration-off and brake-on subsequent to the acceleration-off, and

wherein the deceleration velocity of the vehicle is reduced so as not to delay the acceleration-off in comparison with the predetermined operational timing.
