Title:
車両の安全構成
Document Type and Number:
Japanese Patent JP4442743
Kind Code:
B2
Abstract:
A safety arrangement in a motor vehicle comprises a safety device (38) adapted to protect an occupant of the vehicle in the case of a roll-over accident, and a roll sensor arrangement to provide a signal (33) to trigger activation of the safety device. A sensor (30) senses an angular parameter such as angular speed about the longitudinal axis of the vehicle, or the actual angle of roll about the longitudinal axis of the vehicle. A further sensor (31) senses a velocity parameter relating to the vehicle speed, such as the total velocity of the vehicle, or the velocity of the vehicle in a predetermined direction. A processor (35) senses an angular speed in excess of a predetermined threshold, which activates a timing mechanism (36) which is associated with a processor (34) which compares angular velocity with a threshold, and provides a triggering signal if the threshold is exceeded. The threshold is a function of vehicle speed. The angular velocity is also compared with a further threshold in another processor (32), the threshold in this processor being a function of angle of roll. If this processor generates an output signal, the safety device (38) is activated.
