Abstract
Disclosed is a solution to the use of a speed limiter in a motorcycle that has a high capacity for acceleration, including a method for limiting the speed of a motorcycle using precise parameters of speed, acceleration and required engine torque and a single control button to manage the smart activation and deactivation of the limiter and to input new speed limits Vlim in a simple way. It thus allows the use of a speed-limiting system in a motorcycle that has a high power/weight ratio by avoiding the sources of interference with the riding and the effects liable to jeopardize its stability.
Claims20
A method for limiting a speed of a motorcycle that is equipped with a speed limiter configured to operate, when a motorcycle speed-limiting mode is in an active state, to limit the speed of the motorcycle to a speed limit Vlim, comprising:
- switching the speed limiter from an inactive state to the active state only when:
- an instantaneous speed of travel V of the motorcycle is above the speed limit Vlim and below said speed limit Vlim increased by a determined speed margin value Vth,
- an engine torque CMreq required by the rider of the motorcycle is below an engine torque CM that maintains the instantaneous speed of travel V of the motorcycle, increased by a first determined engine torque margin value CMth, and
- an acceleration of the motorcycle is positive,
- such that the limiter, thus rendered active, commands supply, to the motorcycle, of an engine torque equal in value to CM so as to maintain the instantaneous speed of travel V of the motorcycle;
- and
- switching the speed limiter from the active state to the inactive state when either of
- the engine torque required by the rider is below the engine torque CM decreased by a second determined engine torque margin value Y, or
- the engine torque required by the rider is above the engine torque CM increased by the first engine torque margin value CMth,
- such that the engine torque required by the rider is supplied to the motorcycle.
A control unit for a speed limiter for a motorcycle, the speed limiter configured to operate, when a motorcycle speed-limiting mode is in an active state, to limit the speed of the motorcycle to a speed limit Vlim, the control unit configured to:
- switch the speed limiter from an inactive state to the active state only when:
- an instantaneous speed of travel V of the motorcycle is above the speed limit Vlim and below said speed limit Vlim increased by a determined speed margin value Vth,
- an engine torque CMreq required by the rider of the motorcycle is below an engine torque CM that maintains the instantaneous speed of travel V of the motorcycle, increased by a first determined engine torque margin value CMth, and
- an acceleration of the motorcycle is positive,
- such that the limiter, thus rendered active, commands supply, to the motorcycle, of an engine torque equal in value to CM so as to maintain the instantaneous speed of travel V of the motorcycle;
- and
- switch the speed limiter from the active state to the inactive state when either of
- the engine torque required by the rider is below the engine torque CM decreased by a second determined engine torque margin value Y, or
- the engine torque required by the rider is above the engine torque CM increased by the first engine torque margin value CMth,
- such that the engine torque required by the rider is supplied to the motorcycle.
