Abstract: Wrong way travel detection and control systems and methods for a vehicle utilize a set of perception sensor systems each configured to perceive a position of the vehicle relative to its environment, a map system configured to maintain map data, and a controller configured to receive first information from the set of perception sensor systems and the map system, generate a confidence score indicative of a likelihood that the vehicle is traveling in a wrong direction along a roadway using a vehicle position model and the received first information, compare the confidence score to a set of one or more thresholds, and based on the comparing, selectively control one or more operating parameters of the vehicle to remedy the wrong direction travel of the vehicle.

Abstract: A control system and method of operating a vehicle having an active driver assistance system includes receiving, from a steering wheel torque sensor, a measured torque applied to a steering wheel of the vehicle by a driver of the vehicle, obtaining a steering torque request for an active steering feature of the active driver assistance system, determining a steering torque request limit for the active steering feature based on the measured steering wheel torque, wherein an increase in the steering wheel torque corresponds to a decrease in the steering torque request limit and vice-versa, limiting the steering torque request based on the steering torque request limit, wherein the limited steering torque request is greater than zero, and commanding a steering actuator as part of the active steering feature based on the limited steering torque request, the steering actuator being configured to control steering of the vehicle.

Abstract: A power steering pump comprises a housing that includes a bore, a fluid discharge port that supplies pumped fluid into the bore, and a fluid bypass port for recycling excess fluid to the pumping elements. The pump outlet is at one end of the bore. A flow control valve is slideably received in the bore and regulate the size of the inlet to the fluid bypass port. The pump includes a solenoid assembly that has a plunger that is operatively connected to the flow control valve through the second end of the bore opposite the pump outlet. By adjusting the magnitude of the current to the electromagnetic coil of the solenoid assembly, the position of the flow control valve is varied to increase or decrease fluid flow to the fluid bypass port and thereby regulate the output from the pump.

Abstract: A power steering pump comprises, as main elements, a cam plate, a discharge cover plate and a suction cover plate that cooperate to define a cam chamber, a fluid discharge passage and fluid suction passage for the pump. The cam chamber is formed in the cam plate. The discharge cover plate includes a face that abuts a first face of the cam plate and includes a recess that cooperates with first cam plate face to define a fluid discharge passage. A suction cover plate includes a suction cover face that abuts a second face of the cam plate and comprises a recess that cooperates with the second cam plate face to define a suction passage. The power steering pump further comprises a rotor within the cam chamber and comprising slideable vanes.

Abstract: A power steering pump for an automotive power steering system or the like comprises a housing defining a bore and a fluid discharge port and a fluid bypass port communicating with the bore. A flow control assembly is received in the bore and comprises a cartridge that includes a first opening for admitting fluid from the fluid discharge port and a second opening communicating with the fluid bypass port. A flow control valve slides to open and close the fluid bypass port. The flow control valve is biased in the closed position by a coil spring and a retainer. During assembly of the flow control valve, the coil spring and the retainer within the cartridge, the spring compression force may be measured, and the position of the retainer adjusted, to obtain a predetermined opening force for the valve.
