摘要： PURPOSE:To remove a spear-shaped nozzle superposed on a yaw rate signal with simple structure without causing the phase delay of the signal by providing a digital filter for holding the output value at the time of the rate-of-change of the input value of yaw rate signals inputted from a yaw rate sensor being larger than the set value. CONSTITUTION:An analog buffer 22 takes in signals from a rear wheel steering angle sensor 12 and a yaw rate sensor 18, an A/D converter 23 performs analog digital conversion, and a driving circuit 24 supplies a direct current servo motor 2 with a current corresponding to a current command signal If from a microcomputer 19. The microcomputer judges, on the basis of the signal from the yaw rate sensor 18, whether the absolute value of the difference between the present yaw rate input value uj and the preceding yaw rate uj-1 is larger than the present value (a), and outputs the preceding yaw rate output value yj-1 as the present yaw rate yj when the absolute value of the difference is larger than the preset value (a).

摘要： PURPOSE:To calculate the angular speed by eliminating the unnecessary noise due to the chattering, etc. of a revolved body by installing the second calculating means which receives the detection signal of a steering angle sensor and sets the steering angular speed to zero when the state where the steering angle does not change by a prescribed angle continues for a prescribed time. CONSTITUTION:When the steering angle by a steering angle sensor M1 changes by a prescribed angle, and the time required for this change is over a prescribed time, the first calculating means M2 sets the change angle per the required time as the steering angular speed. Then, the second calculating means M3 sets the steering angular speed to zero, when the state where the steering angle does not change by a prescribed angle continues for a prescribed time. Accordingly, when the backlash of the gear of a steering wheel of an automobile or play in a joint part exist, the state where the steering angle does not change by a prescribed angle continues for a prescribed time, and the steering angular speed is set to zero.

摘要： PURPOSE:To detect the correct angular velocity by estimating the zero point of an angular velocity sensor even when the angular velocity is increased during the movement of a moving body. CONSTITUTION:The angular velocity signal outputted from an angular velocity sensor 11 is made the angular velocity within the preset range by a signal vertical clamp section 16. This angular velocity is integrated by the first integration procession section 19 to estimate the zero point when a vehicle is stopped, and it is integrated by the second integration procession section 20 to estimate the zero point when the vehicle is traveled. The estimated zero point is outputted to an angular velocity calculation section 15, and the true angular velocity is detected from the angular velocity detected by the angular velocity sensor 11 and the estimated zero point.

SOLUTION: The vehicle running supporting device senses an obstacle existing ahead of the vehicle, and in case the obstacle has possibility of colliding, gives an alarm to the driver and executes automatic braking applied to the vehicle concerned within the specified control range on the road. It also senses the number of lanes of the road and the position of the lane on which the vehicle concerned is running on the road. The control range on the road is changed in the crosswise direction of the road in accordance with the number of lanes and the position of the lane. Concretely, the lane on which the vehicle exists and inside of the lanes adjoining thereto are set as the control range in case the road contains two or more lanes. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PURPOSE:To simplify the zero point correction of a steering angle sensor and enable highly accurate rear wheel steering control by performing the zero point correction of the steering angle sensor using operating oil pressure detected by an oil pressure sensor provided in a hydraulic device. CONSTITUTION:A steering control signal for performing rear wheel steering control using a steering angle detected by a steering angle sensor 1 is outputted from a rear wheel steering control means 2, and a hydraulic device 4 is driven/ controlled by an electrical actuator 3 according to this outputted steering control signal to steer rear wheels by hydraulic force. In this case, there is provided a minute steering control means 5 for outputting small steering control signals to perform rear wheel steering control within a small range to the electrical actuator 3. A minumum value detecting means 7 is also provided to detect the minimum value of operating oil pressure detected by an oil pressure sensor 6 in the hydraulic device 4, and when the minimum value of the operating oil pressure is detected, the steering angle is set as the zero point correction value in a zero point correction value setting means 8. The zero point correcting operation based on the zero point correction value set as the steering angle is then executed by a correction computing means 9.

摘要： PURPOSE:To keep the running stability of a vehicle good and at the same time solve the problem that the steering response of the vehicle is slowed when yawing motion of the vehicle body is restrained more than needed by increasing the amount of steering of each rear wheel for restraining yawing motion of the vehicle during deceleration in comparison with during operation at constant speed or acceleration. CONSTITUTION:The rate of yawing motion of a vehicle body is detected by a sensor 1 and vehicle speed is detected by a sensor 2 and also the value of a first vehicle speed function which increases with an increase in vehicle speed is set as a yawing rate function by a first means 3. The set yawing rate function is multiplied by the detected yawing rate and the amount of steering of each rear wheel is decided by a means 4. Further each rear wheel is steered by a means 5 in proportion to the decided amount of steering and in the direction in which yawing motion of the vehicle body is restrained. The decelerated state of the vehicle is detected by a means 6. When the decelerated state of the vehicle is detected a second vehicle speed function whose value is larger than that of the first vehicle speed function for the same vehicle speed is set as a yawing rate factor by a second means 7 in place of the value of the first vehicle speed function.

摘要： PURPOSE:To quickly perform the zero point correction of a handle steering angle by allowing the updating of a zero point correction value executed by an updating means, when a yaw rate sensor is normal, and inhibiting the updating of the zero point correction, when it is abnormal. CONSTITUTION:In the case a yaw rate sensor 73 is normal, detecting signals for showing a handle steering angle, a car speed, a yaw rate and a rear wheel steering angle are stored in a RAM 75d as each sampling data from each sensor 71 - 74, an average value of each sampling data is calculated, a zero point correction value is calculated by a neutral handle steering angle, and a zero point correction of the handle steering angle can be executed. Also, in the case abnormality is generated in the sensor 73, a solenoid valve 43 is switched to an electric conduction state, a table in a ROM 75b is referred to, a target rear wheel steering angle thetar is calculated, rear wheels RW1, RW2 are controlled by the steering angle thetar, and the running stability of a vehicle is held satisfactorily. Moreover, as for the zero point correction of the detected handle steering angle thetaf, an updating processing based on the detected yaw rate is not executed, therefore, even when the sensor 73 is abnormal, the steering angle thetaf can be utilized.
