Claims (8)

1. A device for controlling the vehicle's activatable passenger restraint system, comprising an accelerometer for detecting frontal collision acceleration and providing a primary collision acceleration signal; a lateral collision acceleration sensor for detecting transverse collision acceleration and providing a secondary collision acceleration signal; and a controller that determines the collision velocity and collision displacement values in response to the primary collision acceleration signal. This is achieved by comparing the determined collision velocity value to a function of the collision displacement value, which is inversely proportional to the selected initial value chosen by the secondary collision acceleration signal. This controller then activates the activatable passenger restraint system in response to the comparison of the determined collision velocity value based on the collision displacement function, which is inversely proportional to the selected initial value. 2. The device of claim 1 also includes a collision detection sensor positioned at the vehicle collision site, with a controller that activates the activatable passenger restraint system in response to signals emitted from the collision detection sensor. 3. The device of claim 2, where the collision detection site is an accelerometer. 4. The device of claim 1 in which the collision accelerometer is centrally located within the vehicle with a sensitivity axis parallel to the front-to-rear axis of the vehicle. 5. The method for controlling the vehicle's triggerable passenger restraint system comprises the following steps: frontal impact acceleration detection and provision of a first impact acceleration signal indicating this; transverse impact acceleration detection and provision of a second impact acceleration signal indicating this; determination of impact velocity and impact displacement values in response to the first impact acceleration signal; comparison of the determined impact velocity as a function of the impact displacement, inversely, with a default value selected as a function of the second impact acceleration signal; and activation of the triggerable passenger restraint system in response to the comparison of the impact velocity determined as a function of the impact displacement, inversely, with the selected default value. 6. The methodology of claim 5 further incorporates a procedure for detecting impact acceleration at the site of the vehicle collision and activating the activatable passenger restraint system in response to the impact acceleration detected at the site of the collision. 7. A device for controlling the vehicle's actuated passenger restraint system, comprising a collision accelerometer to detect frontal collision acceleration and provide a primary collision acceleration signal; a sectional collision accelerometer to detect collision acceleration and provide a secondary collision acceleration signal; and a controller that determines the collision velocity and collision displacement values in response to the primary collision acceleration signal. This is achieved by comparing the determined collision velocity value as a function of the collision displacement value, which is inversely proportional to the initial threshold value selected as a function of the secondary collision acceleration signal. This controller then activates the actuated passenger restraint system in response to the comparison of the determined collision velocity value as a function of the collision displacement value, which is inversely proportional to the selected threshold value. 8. The method for controlling the vehicle's actuated passenger restraint system comprises the following steps: frontal impact acceleration detection and provision of a type one impact acceleration signal indicating this; site-level impact acceleration detection and provision of a type two impact acceleration signal indicating this; determination of impact velocity and impact displacement values in response to the type one impact acceleration signal; comparison of the determined impact velocity as a function of the impact displacement value, inversely, with a default value selected as a function of the type two impact acceleration signal; and activation of the actuated passenger restraint system in response to the comparison of the impact velocity determined as a function of the impact displacement value, inversely, with the selected default value.
