Vehicle including a control unit for controlling a coupled engine running mode

摘要

A controller is capable of controlling a coupled engine running mode, in which an engine is coupled to wheels and an engine brake is activated by driven rotation of the engine, and a coasting mode, in which an engine brake force is reduced with respect to that in the coupled engine running mode with mode with the engine brake on, and starts the coasting mode on the basis of the steering angle of a steering member. The controller starts the execution of a first coasting mode when the steering angle is equal to or less than a preset upper limit value and starts the execution of a second coasting mode when the steering angle is greater than the upper limit value. In the first coasting mode, the engine rotation is stopped, and in the second coasting mode, the engine remains rotating.

主权项

1. A vehicle comprising:
an engine; an alternator configured to generate power by rotation of the engine; a battery configured to accumulate power generated by the alternator; a steering member operated by a driver; an electric power steering system configured to assist the driver to operate the steering member by using power of the battery; a steering angle acquisition unit configured to acquire a steering angle of the steering member; and an electronic control unit configured to be capable of controlling a coupled engine running mode, in which the engine is coupled to wheels and engine brake is activated by driven rotation of the engine, and a coasting mode, in which an engine brake force is reduced with respect to that in the coupled engine running mode with the engine brake engaged, and also configured to start the coasting mode based on the steering angle of the steering member; the electronic control unit being configured to start an execution of a first coasting mode when the steering angle is equal to or less than a preset upper limit value and start an execution of a second coasting mode when the steering angle is greater than the upper limit value, the first coasting mode being a coasting mode in which an engine rotation is stopped, and the second coasting mode being a coasting mode in which the engine remains rotating.
