  • Patent number: 9254824
    Abstract: An adaptive anti-collision method for vehicles has steps of creating multiple driving patterns with each driving pattern corresponding to a vehicle speed, a safe distance and a braking distance parameter, such as longer safe distance configured for faster vehicle speed, and higher vehicle speed or shorter safe distance for different road condition, acquiring dynamic information, such as vehicle speed or acceleration, of the vehicle using sensors on the vehicle, combining the dynamic information and drivers' driving behavior to determine a driving pattern through a statistical analysis and a neural network, adjusting control parameters of the vehicle according to the driving pattern for an electronic control unit of the vehicle to issue an alert or activate a braking action according to the driving pattern. Accordingly, the anti-collision method can be adapted to different vehicle speed, road condition and drivers' driving habits for adjusting the safe distance and the braking system.

  • Patent number: 9142132
    Abstract: A collision avoidance system is configured to be installed in a vehicle, and includes a speed sensing unit to sense a speed of the vehicle, a distance sensing unit to sense a distance between the vehicle and a nearby object, an EPB unit to decelerate the vehicle, and a control unit to compute a length of collision time after which the vehicle is predicted to collide with the object according to the speed of the vehicle and the distance between the vehicle and the object, and to control the EPB unit to decelerate the vehicle when the collision time is not longer than a brake time length.

  • Patent number: 9116784
    Abstract: The present invention proposes a system and method for preventing a vehicle from rolling over in curved lane. The road images captured by the image capture devices are used to calculate road information. The road information together with the vehicular dynamic information, such as the speed and acceleration of the vehicle are used to predict the rollover angle and lateral acceleration of the vehicle moving on the curved lane. The height of the gravity center and critical rollover speed of the vehicle moving on the curved lane are worked out and used to define a vehicular rollover index. If the vehicular rollover index exceeds a preset value, the system warns the driver or directly controls the speed of the vehicle to prevent the vehicle from rolling over in the curved lane.

  • Patent number: 8773285
    Abstract: A parking pilot method and a device thereof are disclosed. Image detectors capture surrounding images of a vehicle. A speed detector detects speed of the vehicle. A distance detector obtains distance between the vehicle and a barrier. A processor obtains relative coordinates of the vehicle and parking lot and the angle and width of the parking lot with the images, speed and distances. Thereby, the processor creates a preset parking pilot frame and works out a relative position of the preset parking pilot frame and the parking lot. Then, the processor designates the preset parking pilot frame and the parking lot on a display. According to the information on the display, the driver moves the vehicle to an initial position and makes the preset parking pilot frame coincide with the parking lot. Then, the processor instructs the driver to manually park the vehicle, or automatically parks the vehicle.

  • Publication number: 20110074604
    Abstract: An automatic parallel parking device includes an ultrasonic positioning module and a central controlling unit. The ultrasonic positioning module includes a plurality of ultrasonic sensor units disposed at different locations of the vehicle, and a computation unit. Each of the ultrasonic sensor units detects a distance to each of the first obstacle and the second obstacle. The computation unit has a pre-established space positioning matrix and pre-established approximate coordinate data, and estimates a first actual coordinate position of the first obstacle and a second actual coordinate position of the second obstacle based on the distances detected by the ultrasonic sensor units. The central controlling unit is coupled to the ultrasonic positioning module. The central controlling unit has a pre-established parking path algorithm and a pre-established minimal parking space.
