摘要： PURPOSE:To prevent a vehicle control, based on a wrong acceleration signal, by providing a starting correcting means which decreases an influence of the acceleration signal in the vehicle control for a predetermined period when a vehicle starting condition is detected. CONSTITUTION:A vehicle control device, which performs a control for a control object of a vehicle such as a suspension device, steering device, etc., has a removal means B, for removing a low frequency component of an acceleration signal from an acceleration sensor A for detecting a level of acceleration of acting on the vehicle, to control the control object by a control means C by using the acceleration signal from which the low frequency component is removed. Here a detecting means D, which detects the vehicle transfer-driven from a stopping condition to a starting condition, is provided. When the starting condition of the vehicle is detected, by starting correcting means E, an influence of the acceleration signal in a vehicle control is decreased for predetermined period before the acceleration signal is generated so as to correspond to the acceleration of actually acting on the vehicle.

摘要： PURPOSE:To attain a speed control with high safety, by regarding that the distance between cars has no change as long as the effectiveness is not assured for the data on the distance between cars and therefore preventing a sudden acceleration of the car. CONSTITUTION:A radar device 12 detects the distance between a car and its preceding car by a radar sensor 12A and then feeds a data signal 12B showing a safety speed of the car and a data effectiveness signal 12C showing whether the data is effective or not to a control circuit 1. The circuit 1 receives the repetitive information on the safety speed of car from the device 12 and decides a target car speed in a range that does not exceed the safety speed to start the treveling at a constant speed when a settting operation is carried out. In case the data on the inter-car distance has an abnormal change, the effective signal supplied from the device 12 is turned ineffective. As a result, the safety speed is not rewritten. Thus the value of safety speed is held even though the car reaches a curve and the preceding car gets out of the range of directivity of the sensor 12A.

摘要： PURPOSE: To provide a diagnostic device for electronic control system able to move to a check mode by starting surely a diagnostic program only when desired and without operating a panel that has some fear of a switch fualt or a misoperation. CONSTITUTION: A connector 60 is provided to freely connect and disconnect a check mode setting unit 70 to and from each output signal line of an inside air sensor 14 and an outside air sensor 15 which construct a car air conditioning device. The unit 70 is externally connected at a dealer, for example, and at the same time, forcibly sets each output value of both sensors 14 and 15 at the opposite value corresponding to a prescribed temperature range. A microcomputer 22 starts a diagnostic program 25 to move to a check mode when an IG switch 50 is turned on and as long as the output value of both sensors 14 and 15 are equal to the opposite value corresponding to a prescribed temperature range.

摘要： PURPOSE:To reduce the degree of reduction of an actual speed caused when a set switch is operated, by operating a speed regulating element onto a speed increase side based on the operation of the set switch in a constant-speed running apparatus for vehicles. CONSTITUTION:After a set switch 6 is operated, a throttle valve 2 is given a force displacing same toward full opening by a speed regulating element 1 until a preset time passes. A time of continuation is calculated in proportion to a speed difference representing a variation with time of a vehicle speed from the difference between a target speed and an actual speed, and a time of racing is determined from the calculated time. Thereby the amount of racing operation after the operation of the set switch can be controlled in accordance with a variation with time of a speed signal by a control circuit 5. Accordingly, a signal for operating the throttle valve onto a speed increase side as much as required according to the condition of driving and the slope of a road can be prepared, and thereby the feeling of driving can be made excellent.

摘要： PURPOSE:To substantially decrease a number of circuit elements, by applying analog-digital conversion of signal voltage, equalizing the voltage and performing its decision. CONSTITUTION:One end of a horn 2 is connected to the + terminal of a battery 1 and the other end is connected to one end B of a normally closed contact in a relay 3. One end of a driving coil in the relay 3, having the normally closed contact, is connected to the + terminal of the battery 1 and the other end is connected to a terminal 30a of a control circuit 30. A contact 4 is formed to a lever shape, contacted to a handle and fixed to a body side, and its point end is contacted to a slip ring 5. Further the slip ring 5 is connected to a signal wire 40a of a switch group 40. The control circuit 30 internally comprises a microcomputer 14, having an analog-digital conversion function 14A, internal timer interruption function and external interruption function. Then a release command or the like is given through a buffer 15 by a command from the microcomputer 14.
