Abstract

To provide a drive control device of a moving body capable of increasing a regeneration amount without hindering a driver's brake operation and causing too much deceleration. A drive control device of a moving body that updates a regenerative pattern of a driving motor of the moving body including a brake that generates a braking force by being linked to an operation amount of a brake pedal, the drive control device including an external world information acquisition unit that acquires external world information and a brake detector that detects ON/OFF of the brake, wherein when the brake detector detects ON, the regenerative pattern is changed based on the external world information acquired by the external world information acquisition unit such that a braking distance only decreases.

Claims (23)

1. A drive control device of a moving body that updates a regenerative pattern of a driving motor of the moving body including a brake that generates a braking force by being linked to an operation amount of a brake pedal, the drive control device comprising:

an external information acquisition unit that acquires external information; and

a brake detector that detects ON/OFF of the brake, wherein

when the brake detector detects ON, the regenerative pattern is changed by increasing a regenerative force based on the external information acquired by the external information acquisition unit such that the braking force of the brake decreases while the regenerative force increases thereby improving fuel efficiency.

2. The drive control device of a moving body according to claim 1 , wherein

the external information is a type of a deceleration object, a relative distance, and a relative speed registered in advance.

3. The drive control device of a moving body according to claim 2 , further comprising:

a target behavior operation unit that calculates a target distance and a target speed of the moving body from the type, the relative distance, and the relative speed, wherein

the regenerative pattern is changed such that a speed of the moving body at the target distance is the target speed.

4. The drive control device of a moving body according to claim 3 , wherein

when the brake detector detects ON, torque of the driving motor is changed based on the external information such that deceleration of the moving body only increases.

5. The drive control device of a moving body according to claim 4 , wherein

at least one of the deceleration objects is a preceding vehicle on a traveling route of the moving body.

6. The drive control device of a moving body according to claim 4 , wherein

at least one of the deceleration objects is a red signal stop line on a traveling route of the moving body.

7. The drive control device of a moving body according to claim 4 , wherein

at least one of the deceleration objects is a tollgate on a traveling route of the moving body.

8. The drive control device of a moving body according to claim 4 , wherein

at least one of the deceleration objects is a road curve on a traveling route of the moving body.

9. The drive control device of a moving body according to claim 4 , wherein

at least one of the deceleration objects is a width decreased portion on a traveling route of the moving body.

10. The drive control device of a moving body according to claim 4 , wherein

at least one of the deceleration objects is a downhill grade on a traveling route of the moving body.
