Abstract

There is provided an engine restart control device. A controller is configured to stop an engine which is adapted to generate a driving force for running a vehicle when a predetermined stop condition is met and configured to restart the engine when a predetermined restart condition is met after stopping the engine. A steering torque detector is configured to detect a steering torque of a steering handle which is adapted to be operated by a driver. A reaction force generator is configured to give a steering reaction force to the steering handle. The controller restarts the engine when the steering torque detected by the steering torque detector exceeds a predetermined threshold and control the reaction force generator to give the steering reaction force to the steering handle until the steering torque detected by the steering torque detector exceeds the predetermined threshold.

Claims

1. An engine restart control device comprising:

a controller configured to stop an engine which is adapted to generate a driving force for running a vehicle when a predetermined stop condition is met and configured to restart the engine when a predetermined restart condition is met after stopping the engine;

a steering torque detector configured to detect a steering torque of a steering handle which is adapted to be operated by a driver; and

a reaction force generator configured to give a steering reaction force to the steering handle,

wherein the controller restarts the engine when the steering torque detected by the steering torque detector exceeds a predetermined threshold and control the reaction force generator to give the steering reaction force to the steering handle until the steering torque detected by the steering torque detector exceeds the predetermined threshold.

2. The engine restart control device according to claim 1, wherein the reaction force generator is a motor configured to generate a torque for reducing an operation force of the steering handle by the driver.
