A vehicle hill descent control system and method for controlling a vehicle during a hill descent receives inputs from an accelerator pedal position sensor and a brake pedal sensor. The method controls the engine drivetrain system to engine idling and controls the braking control system to maintain vehicle speed by increasing braking torque to minimize or offset a vehicle speed increase due to gravity. In vehicle hill descent mode, when a vehicle user actuates the accelerator pedal, the engine idling does not change. Instead, the electronic control unit operates to decrease braking torque so the vehicle speed is increased.

Various antilock braking systems, devices, and methods using sensorized brake pads are disclosed. In some embodiments, the present disclosure provides a method for improving the performance of an antilock braking (ABS) and anti-slip regulation (ASR) system of a vehicle. The method can include detecting the actual value of the coefficient of friction (e.g., between a tire and the ground), updating the coefficient of friction during braking using the braking torque data derived from at least one braking pad of each wheel, and adjusting brake force. For example, the brake force can be adjusted as a function of and/or to be approximately equal to the value of the actual tire-road friction during braking.

A detection device for detecting a braking force applied by a brake caliper on a hub holder is configured to be mounted at a fastening interface between the brake caliper and the hub holder and has a low-friction body, a caliper- hub-holder connection element, a sensor element, and an electrical interface. The low-friction body puts into contact the brake caliper and the hub holder at the fixing interface. The caliper- hub-holder connection element, configured to be mechanically connected to the brake caliper and the hub holder, is susceptible of deformation. The low-friction body decouples tightening forces from the braking forces to minimize the effect of the tightening forces on the detection device. The sensor element detects strains and generates electrical signals indicative of detected strains and representative of the braking force. The electrical interface is connected to the sensor element for conducting and making available the generated electrical signals. A method and a system for determining a braking torque are also provided.
