摘要： PURPOSE:To provide a data recorder for vehicle, which securely records prescribed data when vehicle is in an emergency. CONSTITUTION:In a step 102, data from respective sensors are read and they are written into a memory part. When a vehicle emergency state is detected and a data recording stop signal is inputted at that time (step 104), data are written for a prescribed time, and the writing of data is stopped. Thus, data when the vehicle is in the emergency is recorded. In a next step 109, it is recognized whether a data recording stop release signal is inputted or not. When it is judged as affirmative, the state of the vehicle is judged in a step 110. When it is judged that the vehicle in the serious emergency state, the inhibition of writing is set. In a step 112, whether writing inhibition is set or not is recognized. When writing is set, data is preserved and writing is terminated. When writing inhibition is not set, a system shifts to an initial step, and the writing of data is started.

摘要： PURPOSE:To secure a precision in controlling a vehicle interval even in a long vehicle interval area, in which a detecting precision of a vehicle interval is deteriorated. CONSTITUTION:A target vehicle interval required for stopping a vehicle is computed on the basis of a vehicle speed (step 100). It is determined whether the vehicle interval detected by means of a CCD camera is the predetermined value or more (step 102). When the vehicle interval is below the predetermined value, driving force is computed on the basis of the vehicle interval and a relative speed, which is a differential value of the vehicle interval (step 106). When the vehicle interval is the predetermined value or more, driving force is computed only on the basis of the vehicle interval while eliminating the relative speed, whose precision is deteriorated according to the deterioration in a detecting precision of the vehicle interval (step 104). Afterward, a vehicle speed is controlled according to the driving force (steps 110-300).

摘要： PURPOSE:To allow the steering wheel returning operation of a driver with an equal steering feeling regardless of an outside temperature, high or low. CONSTITUTION:A temperature sensor 35 detects an outside temperature. A microcomputer 33 outputs a control signal to an electric motor 22 to control output torque greater at a low outside temperature than at a high outside temperature. The rotation of the electric motor 22 is transmitted to a steering shaft 12 via a small gear 23 and a large gear 21 to assist a steering wheel 11 in returning. As a result, even if an outside temperature is low, the viscosity of oil filled up in and around the shaft 22a of the electric motor 22 and the small and large gears 21, 23 is high and part of the output torque of the motor 22 is wasted with the oil, driving force transmitted from the motor 22 to the steering shaft 12 is equal to that at a high outside temperature, so that the steering wheel can be assisted in returning with equal force regardless of an outside temperature, high or low.

摘要： PURPOSE:To perform return operation of a handle at a constant feeling by a driver regardless of the magnitude of a road surface friction factor. CONSTITUTION:A torque sensor 31 detects torque exerted on a steering shaft 12 and an steering angle sensor 32 detects the steering angle of a handle 11. A microcomputer 33 decides reference self-aligning torque based on a detected steering angle. By comparing the reference self-aligning torque with detected torque (representing actual self-aligning torque from a road surface), the magnitude of a road surface friction factor is decide. When the road surface friction factor is low, output torque of an electric motor is widely controlled based on a decided result, and when the factor is high, the output torque is controlled in a narrow range. When the road surface friction factor is low and self-aligning torque exerted on a steering shaft is small, an assist force of an electric motor 22 to perform return operation of a handle is increased.

摘要： PURPOSE:To provide a power steering device at which opposite direction rotation to a direction helping the energization of the steering torque of a motor is not transmitted to a steering shaft. CONSTITUTION:In the case of steering vehicle wheels being directed to the left, an engaging projection 154 is moved to a clutch unit 50 side as an input shaft 22 rotates, and an engaging member 66 is put into an engaging hole 90. If a motor is rotated to a direction to help the energization of steering torque and a large diameter gear 40 is rotated in the same direction with that of an output shaft 22, the rotation of the motor is transmitted to a steering shaft 12 by the engagement of the member 66 to the hole 90. If the motor is rotated in the opposite direction, rotation is not transmitted as the member 66 is separated from the hole 90 due to the slope effect of respective slopes 80,94 of the hole 90. In the case of steering 11 vehicle wheels being directed to the right, the engaging projection 154 is moved to a clutch unit 110 side, and rotation is transmitted/intercepted by the engagement/separation of an engaging member 118 to/from an engaging hole 130.

摘要： PROBLEM TO BE SOLVED: To let the actual amount of intake air accurately coincide with the target amount of intake air even when the throttle opening is comparatively small while the exhaust of soot and NOx is being eliminated. SOLUTION: Soot and NOx are simultaneously prevented from being exhausted by burning fuel while the exhaust of soot is scarcely produced wherein the amount of EGR gas to be fed into the inside of a combustion chamber 5 is greater than the amount of EGR gas when soot is produced at its peak. In addition, an electronically controlled throttle valve 20 is provided, concurrently, let the aforesaid valve 20 be entirely closed, and subsequently, let the opening of the actual throttle valve accurately coincide with the target opening of the throttle valve by learning the entirely closed position of the throttle valve based on the output signal of a throttle valve position detecting sensor 60 before the negative pressure of an intake pipe is built up along with its cranking when the throttle valve is entirely closed, so that let the actual amount of intake air thereby coincide with the target amount of intake air.
