A trailer braking device includes a trailer having an axle, a pair of hubs each rotatably attached to the axle, and a pair of wheels each removably attached to a respective one of the hubs. A plurality of wheel brakes is each integrated into a respective one of the hubs and a pair of wheel speed sensors is each integrated into a respective one of the hubs. A control unit is attached to the trailer and the control unit is in communication with each of the wheel brakes and each of the wheel speed sensors. The control unit actuates a respective one of the wheel brakes when the wheel speed sensor associated with the respective wheel brake communicates that a rotational speed of the hub associated with the respective wheel brake has begun to oscillate. In this way the trailer is inhibited from beginning to sway while being towed.

Instantaneous Tire Traction Modulating Valves [ITTMV] is a wheels internal and external highly time-sensitive application specific fail-safe electro-pneumatic valve design, valve's current-profile and regulator technique that proactively sense and instantaneously modulate the tire pressure between tire's upper and lower cut-off pressure valves from present/recommended values particularly during imminent/inevitable critical driving situations to mitigating-aquaplaning/hydroplaning, loss of stability/control, over/under steering, loss-of-traction, minimise-emergency/high speed braking distance, roll-over and loss of control due to puncture; by real-time sensing, perform context-aware computing and directing Tyre Pressure Modulating Units [TPMU] to actively modulate the tyre pressure in right time with right pressure on right tyres thereby instantly optimizing footprint/sidewall deformation rate to enhance tire traction simultaneously sustaining stability/steer-ability and restore/optimize to pre-set tyre pressure value immediately after overcoming critical situation for further safe and comfortable driving. Wheel hub housing integrated with rotary-link comprising electrically-insulated conductive-fluidic containers to transfer ITTMV's operational power and control-signal/data to wheels.

An autonomous vehicle has a temperature sensor for sensing an air temperature or a road temperature, a processor communicatively connected to the temperature sensor to receive a signal from the temperature sensor, to process the signal and to generate an estimated instantaneous coefficient of friction between a tire of the vehicle and a snow-covered roadway, and a camera to detect salt and/or sand on the roadway and to apply a salt correction factor and/or a sand correction factor to the coefficient of friction to thereby provide a salt-corrected coefficient of friction or a sand-corrected coefficient of friction.

A parking brake control device controls a hydraulic pressure unit for braking wheels hydraulically and a parking brake device for braking the wheels by transmitting power of an electric motor to the wheels mechanically. The parking brake control device includes a hydraulic brake control unit capable of exercising a hydraulic brake control under which a brake is applied to the wheels by the hydraulic pressure unit, on condition that a signal is received from an actuation switch for actuating the parking brake device, while a vehicle is running, and a pressure decrease rate setting unit configured to set a pressure decrease rate according to a closing condition satisfied upon entry into the closing stage of the hydraulic brake control when a pressure decrease control is exercised in a closing stage of the hydraulic brake control.

Systems, methods, and computer-readable storage media for using neural networks to ensure the braking capabilities of articulated vehicles are adapted to prevent jackknifing. A system can receive operational parameters associated with both a vehicle and a trailer being towed by the vehicle. The system can also identify a current surface condition and predict, using a neural network, road conditions for a portion of the road which the vehicle is approaching. When distinctions between current and predicted, future conditions are defined, and the system can cause modification of the operational parameters of the vehicle and/or the trailer.
