VEHICLE CONTROL DEVICE
First Claim
1. A vehicle control device for a vehicle capable of coasting, in which when there is no acceleration or deceleration request to the vehicle while traveling, power transmission between an engine and drive wheels is cut off and the vehicle is allowed to travel by inertia, comprising:
- a controller which is configured to, in a state in which there is no acceleration or deceleration request to the vehicle while traveling and power is transmitted between the engine and the drive wheels, determine whether or not to implement the coasting by comparing a required deceleration rate that is estimated as a deceleration rate to be later required of the vehicle and a coasting deceleration rate that is estimated as a deceleration rate during the coasting,cut off power transmission between the engine and the drive wheels and implements the coasting in a case where it is determined to implement the coasting, andmaintain power transmission between the engine and the drive wheels in a case where it is determined not to implement the coasting.

Abstract
A vehicle control device is a vehicle control device for a vehicle capable of coasting, in which when there is no acceleration or deceleration request to the vehicle while traveling, power transmission between an engine and drive wheels is cut off and the vehicle is allowed to travel by inertia, wherein in a state in which there is no acceleration or deceleration request to the vehicle while traveling and power is transmitted between the engine and the drive wheels, whether or not to implement the coasting is determined by comparing a required deceleration rate Dt which is estimated as a deceleration rate to be later required of the vehicle and a coasting deceleration rate Dn which is estimated as a deceleration rate during the coasting. Where it is determined to implement the coasting, power transmission between the engine and the drive wheels is cut off and the coasting is implemented, and where it is determined not to implement the coasting, power transmission between the engine and the drive wheels is maintained. As a result, the implementation of coasting that can provide a sense of anxiety or discomfort to the driver can be suppressed.
