Abstract: A portable electronic device, like a cellular telephone is capable of detecting collisions between vehicles and notifying the proper authorities. The device includes a microprocessor and memory, in addition to an accelerometer and global positioning systems receiver. The memory includes at least one filter for screening out false positives, which are false collision detections. In one embodiment, the device determines its velocity. It then checks to see if its velocity falls within a range associated with moving vehicles. If so, the device monitors the accelerometer. When acceleration values in excess of a predetermined threshold are detected, the device pauses and again checks its velocity. If the velocity has fallen from the range associated with moving vehicles to a range associated with a vehicle that has sustained a collision, the device notifies emergency personnel that a collision has occurred.

Abstract: Disclosed is a multi-function illuminating display for a motor vehicle combining an inverse function illuminating engine power indicator, a brake light, directional lights, and park lights. The segmented engine power display is fully illuminated at engine idle. Power display illumination decreases incrementally from each end as engine power increases, with minimum illumination at display center at maximum selected and adjusted power, and no illumination when power is above that point. Decreasing engine power to the maximum power point illuminates the center segments, followed by incrementally illuminating segments adjacent the center, until all segments are illuminated. Center segment illumination is of minimum intensity with increasing intensity of left and right side LEDs. The brake light inhibits power indication and illuminates the display as a brake light. Chasing directional lights have priority over the power indication and park lights, and are brighter than the park lights.

Abstract: A vehicle's operator can signal both the intended relative braking effort, and changes thereto, using a signal with a proportionately scaled and reactive display. A sensor measuring the current proportionate intensity of the intended and applied braking effort is attached to a vehicle's braking system. This sensor sends a signal to the associated external display (which may comprise multiple, separated areas). Each display area then shows that portion of its area commensurate with, or proportional to, the intensity of the intended and applied braking effort. The sensor, signal, and display(s) regularly repeat this at rapid intervals, thereby keeping the display responsive to and in accordance with the current intended and applied braking effort. In one enhancement, the outer limit of the display is activated when any braking effort is made, to enable rapid evaluation by any viewer between the relative effort applied and the potential full effort.

Through the comparison of the two risk dimensions, it is decided whether the automatic vehicle deceleration is to be maintained or whether the braking is to be canceled before the vehicle is brought to a standstill.

Abstract: A brake operation amount detection device detects an operation amount of a brake pedal, and a target deceleration computation device computes a target deceleration corresponding to an operation amount that the driver intends to achieve. Further, an actual deceleration calculation device calculates an actual deceleration. A deviation between the target deceleration and the actual deceleration is obtained as a difference level, and a warning issuing device generates a sound having a volume that increases in accordance with the magnitude of the difference level. Accordingly, in the case that the brake does not act, contrary to the driver's expectation, even when the driver presses down the brake pedal, the driver can recognize a degree of difference from the driver's braking intention, based on the magnitude of the sound. Therefore, the driver does not feel a sense of danger or fear.

Abstract: The present invention addresses the need to sustain brake lights illumination of a motor vehicle at substantially stationary state even after brake pedal is released in order to ensure traffic safety. This device employs a number of commonly available relays not only to sustain the power to the brake lights but also to monitor the state of the movement of the vehicle.
