摘要： A unified control device for a vehicle including an anti-skid braking system and power steering control system is controlled by two microcomputers (4B and 24B). On the basis of the outputs of the torque sensors (1a and 1b, etc.), the first microcomputer (4B) determines the driving direction and torque of the DC motor (9) providing the assisting steering torque for the steering wheel, and outputs the torque signal (T) and the first direction signal (D1) for the DC motor (9). The second microcomputer (24B) generates the brake operation signal (B) on the basis of the outputs of the road wheel velocity sensors (21a through 21d) and the brake switch (22). Further, on the basis of the output of the torque sensors (1a and 1b), the microcomputer (24B) determines the direction of the DC motor (9), and outputs the second direction signal (D2). The motor drive circuit (8) drives the DC motor (9) in accordance with the torque signal (T) and the direction command signal (D), which is output from the AND circuit (40) only when the first and second direction signals (D1 and D2) coincide. Further, the microcomputers (4B and 24B) output first and second fail-safe relay energization signals (F1 and F2), respectively, when the power steering control system and the anti-skid braking system are judged to be operating normally. The power supply control circuit (42) immediately opens the fail-safe relay unit (6B) when neither the first and second signals (F1 and F2) are supplied. However, in the case where only one of the first and second signals (F1 and F2) are supplied, the power supply control circuit (42) defers the interruption of the fail-safe relay unit (6B) until the vehicle stops.

摘要： An automobile speed control system wherein a speed deviation between a desired speed as set by the driver of the vehicle and the current running speed is corrected by changing the pulse width of a pulse signal applied to a throttle valve of an engine through an actuator for driving the throttle valve. The pulse width is calculated in a control circuit every predetermined time interval by using the speed deviation, the acceleration of the speed, the rate of change of the acceleration, and control parameters as proportional coefficient for the acceleration. The control parameters are selected according to the relationship between the acceleration and the rate of change of the acceleration.

摘要： The invention relates to a constant-speed cruise control apparatus for automatically controlling the cruise speed of a vehicle to permit the vehicle to cruise at a constant speed. The gradient of a road is estimated on the basis of an actual cruise speed of the vehicle, the opening of a throttle valve, and cruise performance characteristics of the vehicle which indicates the relationship between the cruise speed and the opening of a throttle valve. If it determines that the road is uphill, and moreover, the absolute value of a speed deviation (i.e., a deviation of the actual cruise speed froma target speed) is more than a predetermined value, shifting down is carried out. Subsequently, if the absolute value of the speed deviation is less than another predetermined value, and moreover, it is determined that the road is downhill, shifting up is carried out. Through such shift-up and shift-down control on the basis of both the speed deviation and the road gradient, it is possible to perform speed change control according to the conditions of the surface of a road, thereby carrying out a highly reliable constant speed cruise of the vehicle.

摘要： A cruise control apparatus for an automobile has a motorized actuator with a motor which adjusts the degree of opening of a throttle valve so as to maintain a desired speed. All or part of the control circuit for the motor is in the form of a hybrid integrated circuit which is mounted on the actuator in a manner such that the actuator can serve as a heat sink for the hybrid integrated circuit. In one form of the invention, the hybrid integrated circuit is mounted on the outer surface of the housing of the actuator motor. In another form of the invention, the hybrid integrated circuit is mounted on the inner surface of the actuator housing. The motorized actuator may be further equipped with a contactless position detector for detecting the rotational position of the output shaft of the actuator motor. The position detector comprises a disk which is rotated by the drive shaft of the actuator, a permanent magnet which is secured to the disk, and two magnetic sensors which detect the magnetic field produced by the permanent magnet. The magnetic sensors are housed within the hybrid integrated circuit.
