Abstract
A controller includes: an automatic shifting control section that carries out automatic shifting control in which a shifting actuator is driven in response to a predetermined automatic shifting command; and an assist control section that, when a predetermined assist condition is met, carries out assist control in which the shifting actuator is driven to assist motion of a manual shifting power transmission mechanism actuated upon operation of a shifting operation member by a driver.
Claims8
A transmission-equipped vehicle comprising a transmission that changes rotational speed derived from rotational power output from a prime mover, the vehicle comprising:
- a shifting operation member operated by a driver;
- a manual linkage that transmits, to the transmission, an operation force applied to the shifting operation member by the driver, the operation force acting as shifting power for a shifting process;
- a shifting actuator;
- an automatic linkage that transmits a drive force of the shifting actuator to the manual linkage, the drive force acting as the shifting power;
- and
- a controller that controls the shifting actuator, the controller comprising:
- an automatic shifting control section that carries out automatic shifting control in which the shifting actuator is driven in response to a predetermined automatic shifting command regardless of operation of the shifting operation member that transmits the shifting power to the manual linkage;
- and
- an assist control section that, when a predetermined assist condition is met, carries out assist control in which the shifting actuator is driven to assist motion of the manual linkage actuated upon operation of the shifting operation member by the driver.
