Abstract
A vehicle includes a slip detection section arranged to detect a slip of a driving wheel based on the rotation speed of the driving wheel and the vehicle speed, and an engine control section arranged and programmed to perform control to decrease the output of an engine when the slip of the driving wheel is detected by the slip detection section. When the automatic clutch is in a half clutch state and the slip of the driving wheel is detected, the engine control section executes neither ignition retarding control on an ignition device nor a fuel injection amount decreasing control on a fuel injection valve, and executes control to decrease an opening of a throttle valve.
Claims7
A vehicle comprising:
- an engine including an ignition device, a fuel injection device, and an electronically controllable throttle valve;
- an automatic clutch disengageable and engageable in accordance with a rotation speed of the engine;
- a driving wheel arranged to be driven by the engine;
- a driving wheel detection sensor arranged to detect a rotation speed of the driving wheel;
- a vehicle speed detection sensor arranged to detect a vehicle speed;
- a traction control device including a slip detection section arranged and programmed to detect a slip of the driving wheel based on the rotation speed of the driving wheel detected by the driving wheel detection sensor and the vehicle speed detected by the vehicle speed detection sensor, and an engine control section arranged and programmed to perform control to decrease an output of the engine when the slip of the driving wheel is detected by the slip detection section;
- and
- a clutch state detection device arranged to detect a state of the automatic clutch;
- wherein
- when the automatic clutch is in an engaged state and the slip of the driving wheel is detected, the engine control section of the traction control device executes at least one of ignition retarding control on the ignition device and fuel injection amount decreasing control on the fuel injection device, and also executes control to decrease an opening of the throttle valve;
- and
- when the automatic clutch is in a half clutch state and the slip of the driving wheel is detected, the engine control section of the traction control device does not execute either the ignition retarding control on the ignition device or the fuel injection amount decreasing control on the fuel injection device, and executes the control to decrease the opening of the throttle valve.
