In the controller and the control method according to the present invention, during the cruise control, in which acceleration/deceleration of the straddle-type vehicle is automatically controlled without relying on an accelerating/decelerating operation by a driver, a vehicle speed of the straddle-type vehicle is restricted to be equal to or lower than an upper limit speed at the time of turning, an exit of a curved road is detected on the basis of a predicted route of the straddle-type vehicle, and a magnitude of the deceleration of the decelerated straddle-type vehicle is reduced at a time point before the straddle-type vehicle reaches the exit.

Methods, apparatuses, and systems for monitoring traction for a single-track motor vehicle are provided. A PID drive slip regulator regulates the drive slip of at least one driven wheel. An actual wheel slip and a target wheel slip are used as input variables of the PID drive slip regulator. The PID drive slip regulator ascertains a wheel drive torque from the sum of a P component, an I component, and a D component of the PID drive slip regulator and provides the wheel drive torque back to the at least one driven wheel. A transverse force potential, which constitutes the maximally transmissible transversal force of the at least one driven wheel onto a lane under current operating conditions, is determined using the I component of the PID drive slip regulator. The target wheel slip is determined using the transverse force potential.

A method for detecting the speed of a bicycle, where the bicycle is equipped with an ABS system on the front wheel, in which, if the rear wheel deceleration is less than a preset threshold value, then the speed of the bicycle is identified with the rear wheel speed. If the front brake circuit pressure is below a preset low pressure threshold, then the speed of the bicycle is identified with the front wheel speed. Otherwise the speed of the bicycle is an estimated speed based on the last known speed and likely deceleration.
