Title: Controller for vehicle safety device
Inventor: OKANO MASAMI
IPC: B60R21/16
Filed: 1989-01-24
Abstract: PURPOSE:To conduct surely the discrimination of the existence of a collision within a required period and conduct a highly reliable control, by detecting the peak value of the positive of a speed change in response to a signal processing means, and deciding the reference level of a collision decision in accordance with this value, and conducting the comparison of a speed change level and the reference level. CONSTITUTION:In the case of a vehicle colliding with an obstackle in front due to the vehicle being hit from behind, the vehicle is accelerated once, and as a result, the speed of the vehicle is increased once, and next, deceleration is made. A peak value at the time of the positive direction change of a speed change which is generated by a vehicle speed being increased once, is detected by means of a peak value detecting means 5 based on an output from an integration means 4, and the reference level for a collision decision is determined in consideration of this detected peak value at a determining means 6. The reference level thus decided and the level of the speed change, are compared by means of a comparison means 7, and the decision of the vehicle collision is conducted based on this comparison outcome.
