A dual direction accident prevention (DDAP) and assistive braking system (ABS) which detects both the risk of a frontal accident and a rear accident and then coordinates braking to prevent both if possible while giving priority to preventing a frontal accident. In the event of an imminent rear collision with an object or vehicle in front of a driver, the system will choose a braking force which minimizes the impact of the rear collision, while determining a safe approach toward the front obstacle. Furthermore, if a vehicle is approaching the driver and an accident is imminent, and there is no further room in front to reduce the effect of the imminent impact, the system prepares the vehicle and driver by bracing for impact by applying emergency brakes, tightening seatbelts, etc.

Described herein are systems, methods, and non-transitory computer readable media for determining a direction of movement of an authority vehicle in relation to another vehicle such as an autonomous vehicle and initiating or ceasing a vehicle response measure that may have previously been initiated based on the determined direction of movement. A signal source associated with the authority vehicle emits a periodic acoustic signal that is received at one or more audio capture devices, which may be provided at various locations on an exterior of a vehicle. One or more signal characteristics of the acoustic signal can be determined such as frequency, sound intensity, and/or phase. Detected signal characteristic(s) of the acoustic signal can be analyzed, and in some cases, compared against known information such as an expected frequency of the acoustic signal to determine the direction of movement of the authority vehicle in relation to the vehicle.

Non-inverted park lock systems and methods include an engine controller configured to control an engine of a vehicle in communication with a separate transmission controller via a controller area network (CAN), wherein the transmission controller is configured to control a transmission of the vehicle; and a conductor connecting the engine controller to a park lock solenoid disposed in the transmission and configured to move a park pawl to engage/disengage park. The engine controller keeps the park pawl disengaged from park during a power loss malfunction at the transmission controller and the transmission controller keeps the park pawl disengaged from park during a power loss malfunction at the engine controller by maintaining hydraulic pressure in the transmission at a threshold level until park is requested via the shifter.

A method for reducing jolt moments during a deceleration of a vehicle by a braking system, the braking system having at least one electrically actuatable pressure supply device, hydraulic wheel brakes and a valve device. The valve device is designed to apply a pressure provided by the pressure supply device to a selectable subset of the wheel brakes. The method includes: determining a braking requirement, determining a vehicle speed, checking whether the vehicle speed is below a defined threshold value, and if the vehicle speed is below the threshold value, selecting the subset of wheel brakes and applying a pressure provided by the pressure supply device to only the subset of wheel brakes, the pressure being determined according to the selected subset of wheel brakes.
