Abstract: A lane detection system for a vehicle includes at least one sensor for sensing lane markers and objects in the vicinity of a host vehicle, a driver interface in the host vehicle, and a controller having control logic. The control logic receives signals from the at least one sensor, determines a present lane of travel based on the sensor signals received, determines that a time that the host vehicle has been in the present lane of travel meets or exceeds a predetermined time, and transmits an alert signal to the driver interface in response to the time meeting or exceeding the predetermined time.

Abstract: Dynamic braking capability of a combination vehicle including a tractor and at least one trailer is provided based on a distribution of the load carried by the combination vehicle. Load distribution is determined directly using load sensors disposed at wheel pairs of the tractor and trailer(s) or indirectly by using a load sensor located at the drive axle of the tractor together with engine torque and vehicle speed signals for determining gross vehicle mass. A database having sub-databases therein each storing stopping distance calculation results for a corresponding combination vehicle type e.g. 5-axle single or 8-axle double, is indexed by using the determined load distributions for providing the dynamic braking capability based on the vehicle type and its load distribution. The database may also be indexed using Axle Load Allocation Factor that is calculated based on a mathematical combination of drive, steering, and gross trailer axle loading.

Abstract: A method and controller are provided for delaying activation of autonomous emergency braking of a host vehicle, based on a determination that autonomous emergency braking is not needed because a forward vehicle in front of the host vehicle is turning out of the path of the host vehicle. The controller receives inputs from sensors arranged on the host vehicle and includes a processor for determining whether and when to activate autonomous emergency braking. The processor includes control logic that determines whether a forward vehicle is present in front of the host vehicle and whether the forward vehicle is expected to turn out of a path of the host vehicle prior to the host vehicle reaching a current position of the forward vehicle. Based on the inputs from the sensors, the control logic determines whether to delay activation of the autonomous emergency braking of the host vehicle for a time value.

Abstract: A controller for use with autonomous vehicle functions comprises an input for receiving data regarding a set of vehicle factors, an output for controlling autonomous vehicle functions and a processor having control logic. The control logic receives data regarding the set of vehicle factors, sets the autonomous vehicle functions in a first mode when at least two of the vehicle factors meet a respective first condition and sets the autonomous vehicle functions in second mode when at least one of the vehicle factors meets a respective second condition.

Abstract: 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.

Abstract: A braking controller and method in a towing vehicle towing one or more towed vehicles as a combination vehicle provides brake control of the one or more towed vehicles based on a level of braking force applied to the towing vehicle. A non-enhanced braking mode applies a first level of braking force to the towed vehicles in a predetermined reduced proportion relative to the level of braking force applied to the towing vehicle, and an enhanced braking mode applies a second level of braking force to the towed vehicles greater than the first level of braking force. A controller deceleration command input receives a deceleration command signal which is compared against predetermined threshold deceleration rate value or against a current deceleration value being executed by the combination vehicle and, based on a result of the comparisons, either the enhanced or the non-enhanced braking modes are implemented by the controller.
