摘要： PURPOSE:To realize good antiskid control by a structure wherein a means for varying the period to permit starting calculation of wheel speed is provided in a vehicular running control circuit so as to execute calculation of wheel speed, which requires comparatively long duration, while putting as little pressure as possible on the remaining processing. CONSTITUTION:Upon the receipt of signals from a single or a plurality of vehicular speed sensors (a),...(b), each of which generates a signal with a frequency in proportion to the rotating speed of a corresponding wheel, a control circuit (e) calculates the wheel speeds corresponding to the wheels and outputs drive signals to regulation members (c),...(d) for running state regulation based upon the calculated wheel speeds. In this case, a means (f) for varying the period to permit starting calculation of wheel speed is provided in the control circuit (e). The means (f) for varying the period is adapted so that the period to permit starting calculation of wheel speed is elongated with the increase of calculated wheel speed over a range from the low speed region to the high speed region of calculated wheel speed.

摘要： PURPOSE:To perform antiskid control so accurately in time of trouble or disconnection happening in a stop switch, by discriminating the braking state of a car on the basis of a wheel slip rate. CONSTITUTION:An antiskid control device is provided with a speed sensor I generating a signal corresponding to the wheel speed of a car and a stop switch IIfor detecting the brake operation of a driver as interlocked with a brake pedal and also provided with a braking discrimination device finding the braking state of the car on the basis of a signal out of at least the stop switch II. And, it also has an electronic control circuit V generating a brake oil pressure control signal IV corresponding to a car running state to be found on the basis of a signal out of the speed sensor I after a fact that the car is in a braking state is judged. In the control discrimination device III, there is provided with a comparator device VI which judges the car is in the braking state at a time when a slip or the like of the car is larger than a preset slip rate.

摘要： PURPOSE:To enable improving of a functional, a constitutional, and a space efficiency, by compounding functionas to control a constant-speed running and to control a car speed alarm. CONSTITUTION:An antiskid controller 100 regulates a brake oil presure so that decelerating tendency of a wheel speed coincides with a reference pattern when a vehicle is decelerated resulting from application of the brake. It also prevents slipping of wheels, and outputs a detecting information signal of a trouble on an electric system at each trouble item. A speed control/water device 200 receives the output of the device 100 to generate a pulse signal synchronizing with a wheel turn of a vehicle, and performs an adjustment of an input signal and an output control signal according to a predetermined control program. A car speed signal of one bit from the device 200 is applied to a self-door locking device 300.

摘要： PURPOSE:To prevent the excessive decompression of a brake hydraulic pressure due to the deviation of wheel speed by transmitting decompression instruction only the time when the wheel speed and the wheel acceleration become less than a standard speed and a standard acceleration respectively for a certain time. CONSTITUTION:A standard speed calculating means III calculates a standard speed as one of the judging criterion on decompressing a brake hydraulic pressure on the basis of the wheel speed calculated by an arithmetic means II. Then, a comparison judging means IV compares the calculated wheel speed and wheel acceleration with the standard speed and the standard acceleration which is predetermined as another judging criterion on decompressing the brake hydraulic pressure, and the time in the case when the former is less than the latter is counted by a counting means V. A decompression instructing means VI adds the counted time as one of the parameters on decompression, when the wheel acceleration is over the standard acceleration and the wheel speed is less than the standard speed. When the above-described time is less than the set time, instruction of decompression is not transmitted.

摘要： PURPOSE:To improve the safety of an automobile by starting processing by a controller after confirming that a runaway detecting circuit operates normally when a power source circuit is turned on. CONSTITUTION:When a start switch 9 is turned on, the runaway detecting circuit 6 enters into self-oscillation at a period T2 and when an operation pulse signal S1 is not inputted from a CPU2, a reset signal S6 is impressed to the CPU2 at intervals of time T2 to reset the CPU2. Once the reset signal S6 is impressed, the CPU2 restarts a program at a starting step. If a fault occurs to the runaway detecting circuit 6 and the reset signal S6 is not impressed to the CPU2, a counted value becomes constant and the CPU2 outputs a warning signal indicating the abnormality to an alarm device 10 to let the driver know the abnormality of the runaway detecting circuit 6.
摘要翻译：目的：通过在电源电路接通后确认失控检测电路正常工作后，通过控制器开始处理，提高汽车的安全性。构成：当启动开关9接通时，失控检测电路6在T2周期进入自振荡，并且当没有从CPU2输入操作脉冲信号S1时，复位信号S6以间隔向CPU2施加的时间T2来复位CPU2。一旦施加了复位信号S6，CPU2就在起动步骤重启程序。如果失控检测电路6发生故障，并且复位信号S6不向CPU2施加，则计数值变得恒定，CPU2向报警器10输出表示异常的警告信号，以使驾驶员知道异常失控检测电路6。

摘要： PURPOSE:To increase the hysteresis of signals and reduce the delay of response by incorporating a backlash circuit into a controlling circuit of the apparatus which controls the air-fuel ratio through the feedback of the signal of an exhaust gas sensor to the intake system. CONSTITUTION:In the exhaust pipe 13 of an internal combustion engine 10, an exhaust gas sensor 14 for detecting the concentration of exhaust gas and tertiary catalysts 15 are arranged, and the signal of the sensor 14 is feedback-treated to an actuator 19 arranged in an intake pipe 11 through a control circuit 33, and thus air-fuel ratio is set at a theoretical air-fuel ratio. In the control circuit 33, a backlash circuit 50 is incorporated which always keeps the hysteresis of signals constant, and the signal from the sensor 14 is introduced through a stabilizing circuit 40, and the signal 61 on starting is introduced through a compensation circuit 60. The signal from the circuit 50 is supplied to a deviation detector 16 and comparison- operated with a prescribed value, and then supplied to the actuator 19 through a temperature correcting circuit.
