摘要： PROBLEM TO BE SOLVED: To provide a control device for vehicle running condition capable of promoting an adequate brake/accelerator operation to a driver while assisting the operation of the driver during the starting operation on an uphill.
SOLUTION: In the control device for vehicle running condition, when the actual advancing direction of a vehicle body is opposite to the desired advancing direction of a driver, "No" is determined in S115, and the program advances to S116. It is further determined whether or not the rotational direction of a wheel is matched with the desired advancing direction of the driver. As a result, when the rotational direction of the wheel is matched with the desired advancing direction of the vehicle body, "Yes" is determined in S116, and the program moves to the control ending in and after S130. Thus, by stepping in an accelerator pedal, the slide-down mitigation control is successively completed from the wheel in which the rotational direction is matched with the desired advancing direction.

摘要： PROBLEM TO BE SOLVED: To restrain wrong determination of an abnormality detecting device by canceling abnormality determination when the wheel speed detection value of a specified wheel is substantially zero, and the wheel speed detection values of other wheels are not substantially zero, and in the case where the rotation of the specified wheel is physically restrained as compared with the rotation of other wheels. SOLUTION: Output signals from the respective wheel speed sensors 10-10z of wheels WFL-WRR are input through an A/D converter 12 to a processor 24 in a control device 100, and the wheel speed is detected by using a program of a ROM 16 to conduct various control. When the wheel speed of a specified wheel is decided to be abnormal, the control device 100 compares the wheel speed average of all wheels with an estimated wheel speed based on the rotating speed of an engine by operation, and determines that there is no abnormality of the wheel speed sensor when these numerical values agree or substantially agree. Thus, abnormality determination in the stack state during running on a bad road by four-wheel drive can be canceled so as to restrain wrong determination.

摘要： PROBLEM TO BE SOLVED: To restrain lag of traction control by obtaining this time reference speed according to a designated wheel speed which is higher than the minimum wheel speed and lower than the maximum wheel speed when the preceding car speed is equal to or higher than a designated value. SOLUTION: Output signals from the respective wheel speed sensors 10-10z of wheels WFL-WRR are input through an A/D converter 12 to a processor 24 in this control device 100, and the wheel speeds are detected by using a program of a ROM 16 to conduct various control. In traction control, when a deviation between a reference wheel speed and a specified wheel speed exceeds a designated value, an actuator ACT for driving a brake is driven to brake the wheel of the high speed side, thereby restraining slip. When the preceding car speed is equal to or higher than a designated value, this time reference speed is obtained according to a designated wheel speed which is higher than the minimum wheel speed and lower than the maximum wheel speed. This car speed is the preceding reference speed or the speed of a vehicle.

摘要： PROBLEM TO BE SOLVED: To provide proper braking for a vehicle if wheels are in a non- grounded condition. SOLUTION: This control device has a center differential via which driving force is distributed to front wheels and rear wheels and transmitted thereto and a braking system for selective switching between braking with the braking operation of a driver and forcible braking with no braking operation to give braking force to each of the front and rear wheels. In this case, whether a vehicle is in an engine brake condition or not is judged (S14) and whether at least one of the wheels is in a non-grounded condition or not is judged (S16), so that braking force is forcibly granted to other wheels while permitting braking force to be granted to at least one of the wheels with the braking operation of the driver when that the vehicle is in the engine brake condition is judged by an engine brake judgement means and that at least one of the wheels is in the non-grounded condition is judged by a non-grounded condition judgement means (S18).

摘要： PROBLEM TO BE SOLVED: To provide a rotating state detecting device for a wheel capable of avoiding an output of an erroneous rotating direction while stopping a vehicle. SOLUTION: A signal input part 10a exactly detects wheel speed and rotating direction of each wheel 12, 14, 16 and 18 in an ECU 10. Based on the results, each computer 10b, 10c and 10d performs an ABS control, a TC control and a VSC control. At this time, generation of a malfunction by an external magnetic field and generation of state hunting for repeatedly switching positive and negative can be prevented while stopping the wheels 12, 14, 16 and 18 because switching of the rotating directions is limited if an arithmetic result of wheel speed is zero. As a result, a state control of the wheel is optimized.

摘要： PROBLEM TO BE SOLVED: To provide a traction control device for a vehicle, offering braking- type traction control to effectively allow a braking pad to be less worn and a driving system to be less damaged even at a lower speed. SOLUTION: This wheel has driving steering wheels 1 (1FR, 1FL, 1RR, 1RL) connected to an engine 5 and a transmission 6. A TRC computer 4 detects the idling of the driving steering wheels 1 with vehicle speed sensors 33 (33FR, 33FL, 33RR, 33RL) and controls an actuator 3, whereby driving force is granted to the driving steering wheels 1 for idling inhibiting control. In case that an engine rotating speed is faster or engine inertial force is larger, namely, a gear ratio is smaller, less braking force to be granted is generated.

摘要： PROBLEM TO BE SOLVED: To provide a vehicular speed information arithmetic device that can more precisely detect speed information such as vehicle body speed from wheel rotating speed. SOLUTION: Wheels 12, 14, 16 and 18 have respective speed sensors 20, 22, 24 and 26. The output of each sensor 20, 22, 24, 26 is inputted into a rotation signal processing part 10a in an ECU 10 for controlling the state of vehicle operation. The rotation signal processing part 10a detects the rotating direction and rotating speed of each wheel 12, 14, 16, 18. The operation of an average driving wheel speed from the rotation information in consideration of, for example, the rotating directions of both driving wheels 16 and 18 can produce a more precise estimate of vehicle body speed and thus an estimate of engine driving force. The use of the speed information improves the controllability of traction control, ABS control and the like.

摘要： PROBLEM TO BE SOLVED: To accurately estimate a shift position of a transmission without requiring a means for detecting the clutch-ON condition. SOLUTION: Velocity ratio Rnw as a ratio of a wheel velocity Vnw of driving wheels to the engine speed Ne is computed (S20, 30), and a shift position Ps is estimated on the basis of the velocity ratio (S40), and change ratio DVnw of the change gear ratio is computed (S50), and change ratio DVnwf of the velocity ratio after the low pass filter processing is computed (S60). Whether the velocity is being changed or not is determined on the basis of the velocity ratio, the change ratio of the velocity ratio and the change ratio after the low pass filter processing (S80, 100), and in the case of NO, whether the shift position renew allowing condition is satisfied or not is determined (S90-110), and in the case of YES, the shift position Ps is renewed to the estimated shift position (S150).
