    Abstract: AN ADAPTIVE BRAKING SYSTEM ON AN AUTOMATIVE VEHICLE FOR CONTROLLING BRAKE PRESSURE. FROM A SIGNAL THAT REPRESENTS ANGULAR VELOCITY OF THE WHEELS, A CONTROL UNIT GENERATES A SIGNAL THAT REPRESENTS WHEEL ACCELERATION OR DECELERATION. IF THE DECELERATION EXCEEDS CERTAIN VALUES OR THE ACCELERATION EXCEEDS A GIVEN VALUE, THE CONTROL LOGIC WILL VARY THE BRAKE PRESSURE TO GIVE MULTIPLE BUILD AND DECAY RATES OF PRESSURE IN THE WHEEL CYLINDER.

    Abstract: An anti-skid control system for operating inlet and outlet valves of a pressure modulator. The control system uses the rate of change of rotational velocity of the wheels to give an acceleration or deceleration signal. After given acceleration or deceleration rates have been exceeded, the appropriate valve is variably pulsed to give brake pressure build and decay rates that are directly proportioned to wheel acceleration or deceleration. A deceleration responsive switch is used to vary the length of the pressure decay cycle to account for varying coefficients of friction. A delay prevents an initial deceleration rate from operating the valves unless the deceleration rate still exists after a time period.

    Abstract translation: 一种用于操作压力调节器的入口和出口阀的防滑控制系统。 控制系统使用车轮转速的变化率给出加速或减速信号。 在超过给定的加速或减速率之后，适当的阀门是可变的脉冲，以产生与车轮加速或减速成正比的制动压力建立和衰减速率。 减速响应开关用于改变压力衰减周期的长度以解决变化的摩擦系数。 延迟阻止初始减速率操作阀门，除非减速率在一段时间后仍然存在。

    Abstract: A FAIL-SAFE CIRCUIT WHICH IS SUITABLY USED IN AN ADAPTIVE BRAKING SYSTEM. NORMALLY, IN KNOWN ADAPTIVE BRAKING SYSTEMS A CONTROL SIGNAL IS APPLIED TO A BRAKE PRESSURE MODULATOR WHICH IS THEREBY CAUSED TO OPTIMIZE THE BRAKING CHARACTERISTICS OF A WHEELED VEHICLE DURING THE TIME THE VEHICLE IS BEING BRAKED. IN THE PRESENT INVENTION A NORMALLY CLOSED MODULATOR LIMIT SWITCH IS PROVIDED WHICH OPENS WHENEVER THE MODULATOR ATTEMPTS TO CONTROL THE VEHICLE BRAKING CHARACTERISTICS. A NORMALLY OPEN BRAKE SWITCH IS CONNECTED ACROSS THE MODULATOR SWITCH THUS SHUNTING THIS LATTER SWITCH WHENEVER THE BRAKE PEDAL IS DEPRESSED. A LATCHING CIRCUIT WHICH IS LATCHED WHEN THE VEHICLE STARTER IS ENERGIZED AND WHICH SUPPLIES POWER TO THE MODULATORS WHENEVER LATCHED, IS SERIALLY CONNECTED TO THE SHUNTED COMBINATION OF BRAKE SWITCH AND MODULATOR LIMIT SWITCH. ADDITIONALLY THE CONTROL SIGNAL IS SAMPLED AT THE LOW VOLTAGE END OF THE LATCHING CIRCUIT BY AN RC CIRCUIT. IF THE DURATION OF THE ERROR SIGNAL IS EXCESSIVE THE VOLTAGE AT THE LOW VOLTAGE END OF THE LATCHING CIRCUIT, THAT IS, THE VOLTAGE ACROSS THE RC CIRCUIT, WILL BUILD TO A LEVEL TO UNLATCH THE LATCHING CIRCUIT. WHEN THE LATCHING CIRCUIT IS UNLATCHED, WHETHER BY THE OPENING OF THE LIMIT SWITCH WHILE THE BRAKE SWITCH IS OPEN OR BY VOLTAGE ACROSS THE RC CIRCUIT, POWER IS REMOVED FROM THE MODULATOR WHICH WILL THUS RETURN TO A NORMAL POSITION AND RESTORE NORMAL VEHICLE BRAKING.

    Abstract: This invention relates to a device providing a warning signal to the vehicle operator when the brake lining has worn a predetermined amount, and more specifically, concerns an electronic control means which is responsive to a probe means inserted in the brake lining for controlling an indicator means that provides a visual indication.
