A control device and a method for controlling traveling speed of a vehicle for the purpose of maintaining a vehicle speed equal to or lower than a pre-set downhill speed. The method comprises simulating a vehicle speed profile for an upcoming road section if braking at a pre-identified power level would currently be requested, thereby obtaining a predicted maximum vehicle speed and a predicted time until a vehicle speed equal to or within a pre-selected interval of the pre-set downhill speed is reached. The method further comprises, if the predicted maximum vehicle speed is equal to or below the pre-set downhill speed and the predicted time is below a preselected threshold time limit, requesting braking at the pre-identified power level or at an adjusted power level.

A vehicle motion management, VMM, system for a heavy-duty vehicle has at least one wheel speed sensor outputs a wheel speed signal indicative of a rotation speed of a respective wheel on the vehicle, at least one inertial measurement unit, IMU, outputs an IMU signal indicative of an acceleration of the vehicle, a motion estimation function estimates a vehicle motion state comprising vehicle speed over ground, SOG, based on the at least one wheel speed signal and on the at least one IMU signal. The motion estimation function estimates a respective SOG error associated with the wheel speed signal as an increasing function of an applied torque to the wheel, and a respective SOG error associated with the IMU signal as an increasing function of a time duration elapsed after calibration of an integrator of the IMU signal. The motion estimation function estimates the vehicle SOG, based on a weighted combination of the at least one wheel speed signal and the at least one IMU signal, where the weights of the weighted combination are determined based on the SOG error associated with the wheel speed signal and on the SOG error associated with the IMU signal.

A method for adapting a braking deceleration for a vehicle comprising a system for avoiding collisions, including an associated traffic sensor system and a force sensor system. An optimal braking deceleration is ascertained for the evasive maneuver. A current driving velocity of the motor vehicle is ascertained, and a value of a transverse acceleration of the motor vehicle is ascertained via the force sensor system. A setpoint value of a transverse acceleration-dependent braking deceleration is determined based on the value of the transverse acceleration. A velocity-dependent braking deceleration is determined based on the driving velocity. The optimal braking deceleration is ascertained based on the setpoint value of the transverse acceleration-dependent braking deceleration and the setpoint value of the velocity dependent braking deceleration such that the optimal braking deceleration has, as a mathematical function of the variables driving velocity and transverse acceleration, an opposite monotonicity with respect to these variables.

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.

A vehicle control device executes deceleration control for automatically decelerating a vehicle for an object that is present in the direction of travel of the vehicle. The vehicle control device executes the deceleration control such that the start timing of the deceleration control and a deceleration-related value that changes due to the deceleration control satisfy a restriction condition. When a specific condition that a traffic congestion or a traffic congestion-causing event that causes the traffic congestion has occurred within a predetermined distance from the vehicle in the direction of travel is satisfied, the vehicle control device eases the restriction condition compared to when the specific condition is not satisfied.
