The controller is further programmed to determine a predicted path of the remote vehicle using the at least one ranging sensor in response to detecting the remote vehicle.

The collision avoidance control section calculates, based on (i) a passing-through period of the lateral moving object in which the lateral moving object passes through an own vehicle course that is a moving course of the own vehicle and (ii) a reaching time of the own vehicle that is a period remaining before the own vehicle reaching a lateral moving object course that is a moving course of the lateral moving object, an operation timing of the brakes for the lateral moving object passing through the own vehicle course before the own vehicle reaches the lateral moving object course, and operates the brakes at the calculated operation timing of the brakes.
ALERT AND CONTROL SYSTEM AND METHOD FOR ASSISTING DRIVER
Disclosed are an alert and control system for assisting a driver and a method thereof, which may accurately determine an actual driving state of a vehicle by determining the driving state of the vehicle based on a gear signal of the vehicle, previous driving state information, movement state information, a first wheel direction signal, and a second wheel direction signal. Further, it is possible to improve control performance to avoid a collision which may be generated in a direction that matches a driving direction of the vehicle by performing a collision prevention control of the vehicle based on the actual driving state and to prevent an unpredicted risk due to an unnecessary alert or control.
Method for determining at least one speed in a rail vehicle
A speed of a rail vehicle equipped with a first chassis unit is determined. A chassis speed measurement variable is provided by a sensor unit. Inertial measurement variables are detected by an inertial measurement unit; a reference speed characteristic value is formed; an inertial speed characteristic value is determined by a calculation unit based on the inertial measurement variables, in a first operating mode, to estimate a deviation in the inertial calculation based on the reference speed characteristic value; the inertial speed characteristic value is determined, in a second operating mode, without taking into account the reference speed characteristic value. If an anomalous provision process of the chassis speed measurement variable is detected by a recognition unit on the basis of a reference characteristic value and the chassis speed measurement value, the inertial calculation is performed according to the second operating mode.

System and Method for Controlling Wheel Brakes on a Trailer in a Tractor-Trailer
A system and method for controlling wheel brakes on a trailer in a tractor-trailer are provided. Upon receiving a command to apply a trailer wheel brake, the system determines a speed of the tractor-trailer responsive to a speed signal generated by a vehicle speed sensor. The system also estimates a threshold speed based on a level of friction between the tractor-trailer and a road surface on which the tractor-trailer is travelling. The system then generates a control signal to control delivery of fluid pressure to the trailer wheel brake. The control signal causes delivery of a first fluid pressure to the trailer wheel brake when the speed meets a predetermined condition relative to the threshold speed and a second fluid pressure, less than the first fluid pressure, when the speed does not meet the predetermined condition.
