摘要： The left and right rear brake systems of a vehicle each are controlled by a respective electric torque motor. A rear wheel braking system controls the current to each of the torque motors so that each rear wheel is controlled to a speed having a predetermined relationship to the corresponding front wheel. The relationship between the motor currents when each wheel speed has been established at the predetermined relationship is used to determine a bias current value used to equalize the gains of the left and right rear brake systems.

摘要： A brake control system is described that maximizes vehicle braking efficiency by first determining, and then cycling wheel brake pressure and consequently wheel slip about, the critical slip value for the road surface. As each road surface has unique tractive characteristics, the amount of brake pressure required to produce critical wheel slip, and hence maximum brake force, varies for different coefficient of friction road surfaces. This invention determines the coefficient of friction for the operating surface and adjusts the system slip threshold to accurately mimic the actual critical slip value for the road surface. The invention then applies and releases wheel brake pressure so as to cycle wheel slip about this critical slip value.

摘要： A brake system for the rear wheels of a vehicle applies brake pressure to each rear wheel so as to establish the rear wheel speed at a predetermined relationship to the speed of the front wheel on the same side of the vehicle. The brake pressure applied to each of the front and rear wheels is limited by antilock controlled braking in response to a sensed incipient lockup condition of the wheel. When a front wheel first enters into an antilock controlled braking, in response to an incipient wheel lockup condition, the brake pressure to the rear wheel on the same side of the vehicle is rapidly increased to induce an incipient wheel lockup condition thereby inducing antilock controlled braking of the rear wheel.

摘要： A brake control system is described that maximizes the braking efficiency of an under-damped actuator, such as a motor-driven linear screw. When an incipient lock condition is detected, the system determines the optimal brake pressure, relieves brake pressure and measures the duration of the pressure release. When the wheel is approaching recovery, but has not yet substantially recovered, the system holds brake pressure constant at a value calculated to represent the amount of pressure remaining at the wheel brake. This calculated hold value is based upon the measured optimal pressure and the measured release duration, and allows the wheel to continue to reaccelerate towards recovery while preventing unnecessary pressure relief. Once the wheel recovers, the system reapplies brake pressure to a substantial fraction of the optimal pressure without over-exciting the actuator and over-shooting the desired pressure.

摘要： An electric braking system controls the vehicle brake torque based on the pressure applied by the vehicle operator to the vehicle brake pedal and a moving vehicle brake system gain to provide normal power assisted braking while the vehicle is moving. The deviation of the vehicle braking condition from a level incline and lowest vehicle weight (LVW) is determined based upon a determined percent difference between the actual vehicle deceleration while the vehicle is being braked to a stop and an expected deceleration that would result from the total brake torque, a level road surface, and the vehicle weight at LVW. The expected deceleration is determined by determining the total vehicle brake torque represented by the sum of the brake torques applied by the individual wheel brakes and dividing by the LVW of the vehicle. The target torque required to hold the vehicle when stationary is then determined by adjusting a minimum torque value, corresponding to a level road surface and the vehicle weight at LVW, based upon the percent difference in the deceleration values. Finally, a static gain of the electric braking system is determined by dividing the required torque by the operator applied pedal pressure. When the vehicle comes to a rest, the brake system gain is adjusted to the static gain to establish the brake torque at the lowest level required to hold the vehicle stationary on the road surface to thereby minimize static braking actuator current.
摘要翻译：电动制动系统基于车辆操作者对车辆制动踏板施加的压力以及移动的车辆制动系统增益来控制车辆制动转矩，以在车辆移动时提供正常的辅助制动。车辆制动条件与水平倾斜和最低车辆重量（LVW）的偏差基于车辆正在制动到停车时的实际车辆减速度与由总计制造的预期减速度之间的确定的百分比差异来确定制动扭矩，水平路面以及LVW处的车辆重量。通过确定由各个车轮制动器施加的制动转矩和车辆的LVW除以总和的总车辆制动转矩来确定预期减速度。然后，通过基于减速度值的百分比差来调整对应于水平路面和LVW处的车辆重量的最小扭矩值来确定在静止时保持车辆所需的目标扭矩。最后，电动制动系统的静态增益通过用操作者施加的踏板压力除以所需的扭矩来确定。当车辆休息时，制动系统增益被调整到静态增益，以将制动器扭矩建立在将车辆固定在路面上所需的最低水平，从而最小化静态制动致动器电流。

摘要： Vehicle wheel slip is controlled by an add-on brake pressure modulator that may function in addition to limit the brake pressure applied to the vehicle wheels during anti-lock braking. A piston is moved in a cylinder to regulate the braking pressure. During non-operating conditions of the modulator the piston is moved to provide minimum cylinder volume to be in condition to be moved to withdraw fluid from the brake system to limit brake pressure. When a potential for excessive slip of a driven wheel is detected, the piston is moved to increase the volume of the cylinder to draw in braking fluid from a reservoir. The modulator is then in condition to apply regulated brake pressure to limit excessive slip. When the potential for excessive slip no longer exists, the piston is controlled to provide minimum volume while returning the brake fluid to the reservoir. The modulator is then again in condition for limiting brake pressure.

摘要： An excessive slipping condition of one of the driven wheels of a vehicle that is indicative of a loss of traction of that wheel is sensed based on the difference in the driven wheel speeds. An increasing braking force is applied to the wheel with excessive slip to transfer driving torque through the differential to the non-slipping wheel so as to equalize the driven wheel speeds. In order to provide for compensation of the difference in wheel speeds that is not due to slip that occurs as the vehicle is turning, the speeds of the driven wheels are compensated based on the difference in speeds of the undriven wheels.
