Abstract: An autonomous braking system includes a detecting module, a tracing module, a collision path prediction module, a memory register, a collision time prediction module and a decision module. The detecting module recognizes multiple objects located ahead of a vehicle, and then the tracing module traces the moving objects. The collision path prediction module is used to obtain a possible collision range and a non-collision range. The memory register records the coordinate of the objects located within the possible collision range. When one of the objects moves out of the possible collision range, its data is instantaneously removed from the memory register. The collision time prediction module predicts a collision time between the vehicle and each of the objects. The decision module determines if a brake assist is activated in accordance with the collision time.

Abstract: An active vehicle with variable inclination mechanism is provided. The active vehicle with variable inclination mechanism comprises a linear slide mechanism, two sets of longitudinal interlocking mechanism, a steering control mechanism, and a control unit. The linear slide mechanism comprises a reciprocating action member. A lateral displacement of the reciprocating action member drives the longitudinal interlocking mechanism to produce a displacement along a longitudinal direction while a torque is applied at the steering control mechanism. The wheels are driven to move along an opposite longitudinal direction and to form an inclination. Using the active vehicle with variable inclination mechanism can provide a real-time inclination force while rounding a corner as well as increase the safety. Besides, the driver can easily get on/off the vehicle when the vehicle is stationary and the reciprocating action member is locked at the stationary position of the vehicle.
