Method and device for controlling rear-end collision of vehicles in time of tire burst

Abstract: The invention discloses a method and a device for controlling rear-end collision of vehicles in time of tire burst A self vehicle is provided with a transverse angular velocity sensor and a vehicle speed sensor and comprises tire pressure detection modules, a controller, a first wireless transceiver module and a rear vehicle detector, wherein each tire pressure detection module is arranged in a corresponding tire, the first wireless transceiver module is arranged in a carriage and used for receiving tire pressure signals, and the rear vehicle detector is arranged at the rear portion of the carriage Each tire pressure detection module comprises a microprocessor, a second wireless transceiver module and a sensor module The controller is electrically connected with the tire pressure detection modules, the first wireless transceiver module, the vehicle speed sensor, the rear vehicle detector, the transverse angular velocity sensor, a brake generating device and a vehicle power system By the method and the device, the vehicle self can be controlled to be braked to slow down in time of the tire burst according to the speed of the same and the rear vehicle as well as the distance from the rear vehicle

Rear under-ride protection device of car

Abstract: PROBLEM TO BE SOLVED: To provide a rear under-ride protection device of car capable of avoiding rear end collision effectively by informing the following driver or both the river concerned and following driver automatically that a rear-end collision is likely to happen. SOLUTION: A range finder is installed on a car 2 to measure the distance from the car concerned to the following car 3, and an information device 5 is mounted on the car concerned 2 to inform the driver concerned and the following driver that the distance between them obtained by the range binder 4 lies within the set value.

Preliminary studies of mono-pulse braking haptic displays for rear-end collision warning

Abstract: This paper summarizes two studies of mono-pulse braking for rear-end collision avoidance applications. The first study was a single-vehicle parameter-setting study without a lead vehicle that produced recommended pulse braking display duration and jerk rate. However, results also indicated that pulse braking display magnitude influenced the magnitude of driver braking behavior. A second study examined the impact of this driver interface concept both when a lead vehicle was braking to a stop and when the display came on even though the lead vehicle was not slowing down. The results indicated that in the first case drivers modulated their response according to the constraints of the situation rather than the magnitude of the haptic display. On approximately one-third of false positive trials, brief and mild inappropriate braking responses were recorded.

In-depth investigation and reconstruction of an air bag induced child fatality

Abstract: A minor rear-end collision resulted in the death of a four-year old child, occupying the right-front seat of the striking vehicle. The child was restrained by means of a lap belt, the shoulder portion of the belt system having been placed behind the child's back. The child was leaning forward, when the vehicle's brakes were suddenly applied, just prior to the crash. The passenger air bag deployed and the child sustained fatal neck injuries. The case incident was subject to an in-depth collision investigation. Physical evidence associated with the crash, combined with witness statements, and medical data, enabled the vehicle dynamics, occupant kinematics, and occupant contract points to be accurately determined. The collision was subsequently reconstructed using an instrumented child dummy and static deployment of exemplar air bags. A car to rigid barrier dynamic test was also conducted. High-speed film and video recordings of the tests revealed that even minor changes in the position of the dummy had considerable effect on the post-deployment kinematics. Combining the experience gained from a number of such trials, the real-world event was successfully reconstructed in the laboratory. (A) For the covering abstract see IRRD E102514.
