摘要： PURPOSE: An engine torque calculating method using the steering angle is provided to secure the marketability of the engine by using the conventional engine torque in a BJ clipped corner safety region. CONSTITUTION: An engine torque calculating method using the steering angle for preventing the breaking of a birfield joint combined to a drive shaft during a backward movement stall comprises the following steps: comparing the steering angle(315) with the BJ intensity danger angle(310); comparing the steering angle with the NON-VRS full turn angle(320); applying different weight to the steering angle by the size of the steering angle bigger or smaller than the NON-VRS full turn angle; setting correction factors by the relational expression of the steering angle and the BJ intensity danger angle; and calculating the corrected torque by the relational expression of the correction factors and the applied weight. The BJ intensity danger angle is 500 degrees. The NON-VRS full turn angle is 535 degrees.

摘要： 본발명은조타각을이용한엔진토크산출방법에관한것으로서, 후진스톨시드라이브샤프트와결합되는버필드조인트의파손을방지하기위하여정된엔진토크를산출하는방법에있어서, 조타각을 BJ 강도위험각과의대소를비교하는단계; 상기단계에서조타각이 BJ 강도위험각보다큰 경우에는상기조타각을 NON-VRS 풀턴각과의대소를비교하는단계; 상기단계에서상기조타각이 NON-VRS 풀턴각보다큰 경우와작은경우에대하여각각다른가중치를부여하는단계; 상기조타각과 BJ 강도위험각과의관계에따라보정계수를설정하는단계; 상기보정계수와상기가중치의관계식에의하여수정토크를산출하는단계; 로이루어지되, 상기에서조타각이 BJ 강도위험각보다작은경우에는가중치를 0으로하여기본토크에수정을가하지않는것을특징으로하는조타각을이용한엔진토크산출방법을제공하여, 입력토크를 BJ 절각위험각과 NON-VRS 풀턴각을기점으로하여저감시킴으로써 BJ 절각이증가하더라도파단이되지않도록하는효과가있다. 즉, BJ 절각안전영역에서는종래의엔진토크를그대로사용함으로써상품성을유지하고, BJ 절각위험영역과 VRS 시스템적용영역에서는엔진토크를저감시킴으로써버필드조인트의사이즈를축소시킬수 있다. 또한, VRS 시스템적용시조타이질감을해소할수 있는효과가있다.

摘要： A control device of a suspension spring in a vehicle is provided to hold the suspension spring firmly, to reduce noise up of a hood, and to prevent torque steer and shudder phenomena by fixing two upper and lower hook members at catching members when bilateral pistons are extended. A suspension spring is installed with a hook member(5) for restricting tensile motion of the suspension spring when accelerating a vehicle and limiting rebound motion of the suspension spring. The hook member has upper and lower hook members connected with upper and lower parts of the suspension springs respectively. The upper and lower hook members are connected by a corrugation(6). A control unit limits the extended or contacted motion of the corrugation. The control unit has two catching members, a bilateral piston, and an ECU(Electronic Control Unit). The bilateral piston is connected with a hydraulic power unit(12) for supplying or draining hydraulic pressure. A control valve(10) controls a connecting path between the hydraulic power unit and the bilateral piston.
