A method for the assisted emergency braking of a vehicle, in which the lateral and/or the longitudinal guidance of the vehicle are/is influenced in such a way that the vehicle is guided in the direction of a safety zone, and when the safety zone has been reached, a parking position, in particular within the safety zone, is ascertained for the vehicle, the vehicle being guided in such a way that the vehicle comes to a standstill in the parking position.

A brake control unit (50) is provided to drive a brake actuator. The brake control unit comprises a primary control branch (510) with a primary inverter (512) and a primary EMI-filter (517) and a secondary control branch (520) with a secondary inverter (522) and a secondary EMI-filter (527). The primary control branch is configured to provide drive signals (D.sub.10) to the brake actuator in a normal operational mode. The secondary control branch (510) is configured to provide drive signals to the brake actuator in the at least a second operational mode. During the first, normal operational mode, both the primary EMI-filter and the secondary EMI-filter are coupled with their input to the power source. Therewith an improved reduction of conducted electromagnetic interference is achieved.

Systems and methods for monitoring the integrity of a convoy of vehicles are described. The convoy can include a first vehicle and at least one second vehicle connected to the first vehicle. In one example, the system can include a communication line and a power supply line each arranged to be installed in the first vehicle and in the at least one second vehicle. The system can further include a control circuit arranged to verify whether the communication line is interrupted and verify whether the power supply line is interrupted. From the verifications, the control circuit may determine that both the communication line and the power supply line are interrupted and further determine that the second vehicle has disconnected from the first vehicle.

A control arrangement and a method for deactivating an adaptive cruise control system. The method comprises, in response to a determination of risk of loss of functionality of the adaptive cruise control system while the host vehicle is decelerated by the adaptive cruise control system, determining whether the host vehicle may be braked by the service brake system; and, if so, activating a first failure mode during which the adaptive cruise control system is maintained active to decelerate the host vehicle until a deceleration demand is below a predetermined threshold. The method further comprises, when the deceleration demand is below the predetermined threshold, either ramping down the braking demanded by the adaptive cruise control system over a predetermined period of time and thereafter deactivating the adaptive cruise control system, or directly deactivating the adaptive cruise control system.

A method of controlling operation of a vehicle is disclosed, wherein the vehicle comprises an auxiliary braking system and a number of wheel axles each comprising wheels and wheel brakes controllable to brake the wheels, and wherein one or more of the number of wheel axles is a liftable wheel axle. The method comprises the step of controlling at least one of the one or more liftable wheel axles from a lifted position to a lowered position if the at least one liftable wheel axle is in the lifted position and a ratio between an estimated braking capacity of the auxiliary braking system and a current or impending braking need of the vehicle is below a first threshold ratio. The present disclosure further relates to a computer program, a computer-readable medium, a control arrangement, and a vehicle.

Disclosed is an acceleration limit function relaxation apparatus. The apparatus may determine, based on information indicating manipulation of a brake pedal of a vehicle during an acceleration limit mode, that the vehicle is in a temporary braking state, determine a vehicle speed, measured at a start of the manipulation of the brake pedal, as a target vehicle speed for reacceleration, determine, based on information indicating manipulation of an accelerator pedal, that the vehicle is reaccelerated, determine an acceleration limit relaxation factor based on a cumulative braking amount calculated by measuring amounts of braking during the temporary braking state, and cause acceleration limit relaxation of the vehicle by applying the acceleration limit relaxation factor to an acceleration limit of the vehicle.

A computer system including processing circuitry configured to obtain light data from a light-based scanning device; obtain trajectory data of an upcoming trajectory of a vehicle; generate a frame of reference for the light-based scanning device, the frame of reference indicating positional relationships of a plurality of light points based on the light data and a plurality of trajectory points based on the trajectory data; for one or more given trajectory points, identify a non-overlapping region in the frame of reference where no light points are collocated at the one or more given trajectory points; and determine the lens coverage condition based on a position of the vehicle in relation to the identified non-overlapping region.

When it is determined that there is a possibility that an object collides with the vehicle from behind while the vehicle is stopped, collision-corresponding braking control is performed to apply a braking force necessary for suppressing the forward movement of the vehicle due to the collision of the object to the vehicle. During the collision response braking control, it is determined whether or not a backward acceleration caused in the vehicle by the collision of the object has occurred, and in the collision response braking control, when the depression operation of the accelerator pedal is performed while the backward acceleration is occurring, the collision response braking control is continued and the depression operation of the accelerator pedal is not performed.
