TL;DR: In this paper, the authors set up a six-axle plane dynamic model for simulating the yaw/roll stability of heavy tractor semi-trailer using Matlab/Simulink.
Abstract: The active safety and stability of tractor semi-trailer have becoming big concern among the road transportation industry. The paper sets up a six-axle plane dynamic model for simulating the yaw/roll stability of heavy tractor semi-trailer using Matlab/Simulink. LQR controller is chosen to produce the optimum compensate yaw moment to correct the vehicle path based on the bias of yaw rate and lateral acceleration respective. The allocation strategy of braking moment can allocate the braking moment to unique wheel at particular moment, which is the differential braking. At the same time, PD controller can regulate the longitudinal slip ratio of tires to make it work at optimum slip ratio nearby to obtain maximum brake force. The simulation results show that yaw-roll stability of tractor semi-trailer has improved effectively after applying the differential braking.

Abstract: Methods and systems employing the same for controlling braking characteristics of a vehicle are provided. Expected braking characteristics of the vehicle are received and driving condition data is continuously received. A determination as to whether the expected braking characteristics can be safely applied in view of the driving condition data is continuously made and the expected braking characteristics are applied when they can be applied safely.

TL;DR: In this paper, an independent claim is included for a method for generating a braking force in a vehicle, particularly in a partial, high or fully automatically operated vehicle, where the braking effect generated by the former pressure generating unit is greater than or equal to a predetermined operating braking effect.
Abstract: The brake system (1) has two brake circuits with two pressure generating units, which are supplied with energy from two energy sources. A single error in the brake circuits is detected, where the faulty brake circuit is deactivated and a functional brake circuit is activated. A braking effect generated by the former pressure generating unit is greater than or equal to a predetermined operating braking effect, where another braking effect generated by the latter pressure generating unit is greater than or equal to the predetermined operating braking effect. An independent claim is included for a method for generating a braking force in a vehicle, particularly in a partial, high or fully automatically operated vehicle.

TL;DR: In this paper, the braking system has a master braking cylinder (1), responsive to the depression of the brake pedal, coupled to each wheel brake via a dual braking circuit (I,II) incorporating blocking valves (7,8,20) allowing the anti-locking braking regulation.
Abstract: The braking system has a master braking cylinder (1), responsive to the depression of the brake pedal, coupled to each of the wheel brakes via a dual braking circuit (I,II) incorporating blocking valves (7,8,20) allowing the anti-locking braking regulation. The two braking circuits (I,II) are coupled to a supply system after the braking regulation valves (6,7,20) which allows them to be supplied with different brake fluid pressures. Pref. the supply system includes at least one supply valve (43) with a magnetic non-return valve (83,84) between the latter and the braking circuits (I,II).

TL;DR: In this article, a magnetorheological brake with serpentine flux type for ankle-foot orthosis (rehabilitation device) was assessed its performance regarding braking torque and dynamic range.
Abstract: A magnetorheological brake (MRB) with serpentine flux type for ankle-foot orthosis (rehabilitation device) was assessed its performance regarding braking torque and dynamic range. This assessment was conducted based on a problem that the MRB did not generate sufficient braking torque for the orthosis device. The braking capability was appraised through analytical approached based on the prototype design. The magnetic circuit of the MRB design was firstly investigated its capability for generating magnetic flux at braking surface area using finite element method magnetic (FEMM) software. Governing equation was derived to determine the braking performance i.e. braking torque and dynamic range as a function of applied current. The main factors influencing the braking performance were magneto-induced shear stress, the clearance between rotor and stator, and braking surface area. Especially for shear stress, this factor was totally influenced by the magnetic flux generated within the braking area. These all fa...
