Abstract: A vehicle includes at least one brake assembly configured to brake at least one wheel of the vehicle in response to an applied voltage. A power supply is in signal communication with the at least one brake assembly. The power supply is configured to operate in a first mode that outputs a first voltage and a second mode that outputs a second voltage greater than the first voltage. A brake control system is in signal communication with the at least one brake assembly and the power supply. The brake control system is configured to determine a driving state of the vehicle, and is configured to output a brake boost request signal to initiate the second mode of the power supply in response to detecting the driving state, wherein a braking response time of the at least one brake assembly is improved in response to applying the second voltage.

Abstract: Methods and systems are provided for aligning a steering system of a vehicle. In one embodiment, a method includes: determining when the vehicle is driving a straight-line path; determining a steering wheel position error when the vehicle is driving the straight-line path; computing a rear wheel steering offset based on the steering wheel position error and a closed loop control method; and generating a control signal to a rear wheel steering system based on the rear wheel steering offset.

Abstract: A brake pad life monitoring system can monitor the wear of a brake pad operatively coupled to a rotor. The brake pad life monitoring system includes an erodible, electrically non-conductive covering layer operatively coupled to the brake pad such that wear of the erodible, electrically non-conductive covering layer corresponds to the wear of the brake pad. Further, the brake pad life monitoring system includes an electrical circuit having a circuit path from a power supply to a ground. The electrical circuit is at least partially disposed on the erodible, electrically non-conductive covering layer and includes a first resistor connected in series with the power supply and a second resistor electrically connected in parallel with the power supply. The brake pad life monitoring system additionally includes a measuring device electrically connected to the electrical circuit.

Abstract: A brake pad monitoring sensor includes an erodible, electrically non-conductive body, and an electrical circuit disposed within the body. The electrical circuit includes a first wear indicating portion. Electrical continuity of the first wear indicating portion is broken when the body erodes, in response to abrasion against a brake rotor, beyond a first depth relative to a contact surface of the body, to sense a first degree of wear. The electrical circuit includes a first thermocouple that is operable to generate a temperature dependent voltage signal for sensing a temperature of the brake pad. The brake pad monitoring sensor may be used to determine both brake pad wear, and brake pad temperature.
