Abstract: The present invention is a conversion kit to turn a new or used golf car from a conventional, two-wheel drive to a four-wheel drive vehicle. The four-wheel drive system can be engaged while static or while moving at any speed, forward or reverse. The kit has, in its simplest form, a CVT driven sheave adapter, a sprocket, and chain connecting to another sprocket. This combination drives a gear box which, in turn, rotates a drive shaft that connects to a differential. The differential transmits power to the previously non-driven set of wheels and thus turns the vehicle to four-wheel drive. The drive shaft may be made of a single shaft or may be multiple shafts coupled together depending upon the make and model of the golf car. The key advantages of this conversion kit are that it uses the existing drive train to accomplish its goal and is very cost effective and durable. The used golf car market can benefit from this conversion kit in that a four-wheel drive golf car has many more potential customers than a conventional two wheel drive golf car. The conversion kit can also be factory installed by manufacturers of golf cars and utility vehicles. Preventing damage to the turf and the safety of the riders are also key advantages of the conversion kit.

Abstract: In steering control for individually controlling wheel steering angles null1, null2, null3, and null4 of a vehicle in accordance with a condition equation for forming a prescribed mode, one of the condition equation variables is used as a steering command value S. In a process for changing the command value S from a value S1 to a value S2, for transitioning the steering angles null1, null2, null3, null4 from values nullnull1, null2, null3, null4nullS1 corresponding to the steering command value S1, to values nullnull1, null2, null3, null4nullS2 corresponding to the steering command value S2, the steering angles null1, null2, null3, null4 are changed toward incremental transition steering angles nullnull1, null2, null3, null4nullS1nullnullS corresponding to a steering command value (S1nullnullS), which is the steering command value S1 to which an incremental steering command value nullS has been added. After the steering angles null1, null2, null3, null4 reach their incremental transition steering angles and steering angle conformance is detected, the angles are changed toward incremental transition steering angles nullnull1, null2, null3, null4nullS1nullnnullS corresponding to a steering command value (S1nullnnullS), which is the steering command value to which an incremental steering command value nullS has been added nulln timesnull in succession. nullThis is repeated as many times as requirednull to change the steering angles null1, null2, null3, null4 from nullnull1, null2, null3, null4nullS1 to nullnull1, null2, null3, null4nullS2.

Abstract: An electric steering control device is provided which is capable of enabling the driver to perform steering manipulation stably without being substantially affected by the ambient temperature and the heat generation of the control device. The control d vice comprises a temperature sensor for detecting the temperature of a circuit board mounting a motor drive circuit thereon and a compensation section for compensating an electric current command value based on the board temperature detected by the temperature sensor, so that en electric motor for exerting an assist force on a vehicle steering mechanism is driven by the compensated electric current command value output from a motor drive circuit. Therefore, the steering operation can be done stably without being substantially affected by the ambient temperature and the heat generation of the control device. In particular, since the temperature sensor is arranged not on the motor drive circuit per se but on a circuit board mounting the motor drive circuit thereon, the freedom can be heightened in arranging the temperature sensor. Further, since the temperature sensor for heat control of a spiral cable provided on the electric motor is utilized also for compensation of the electric current command value, the components for the control device can be reduced in number.

Abstract: In the conventional electric power steering control system, a steering force applied by a driver to a steering wheel is detected and a torque of a motor is determined on the basis of the detected steering force. In such a prior system, at the time of going round a gentle curve, going round an intersection at an extremely low speed or the like, any steering wheel return torque is not generated unless the driver returns the steering wheel, and drive feeling is not improved. First, a road surface reaction torque estimator 15 estimates a road surface reaction torque on the basis of a steering wheel angle. A neutral point learning unit 24 and a neutral point compensator 25 learn a neutral point of the steering wheel on the basis of the road surface reaction torque with respect to the steering wheel angle. A return torque for returning the steering wheel to the neutral point is computed from a difference between a current angle of the motor and the learned neutral point. As a result, the steering wheel returns to the neutral point under the current driving condition without application of any force to the steering wheel by the driver.
