Embodiments of the invention include a vehicle telematics system including a telematics device and a remote server system, wherein the telematics device obtains sensor data from at least one sensor installed in a vehicle, calculates peak resultant data based on the sensor data, generates crash score data based on the peak resultant data and a set of crash curve data for the vehicle, and provides the obtained sensor data when the crash score data exceeds a crash threshold to the remote server system and the remote server system obtains vehicle sensor data and vehicle identification data from the vehicle telematics device, calculates resultant change data and absolute speed change data based on the obtained sensor data and/or the vehicle identification data, and generates crash occurred data when the resultant change data exceeds a first threshold value and when the absolute speed change data is below a second threshold value.

A body component of a vehicle can comprise a first substrate formed of at least one non-conductive material and defining a back surface that defines a retroreflector geometry and a front surface that defines a different geometry than the retroreflector geometry, wherein the front surface of the first substrate is an exposed A-surface of the body component. The body component can further comprise a conductive layer formed of a conductive material and arranged adjacent to the back surface of the first layer, the conductive layer (i) also defining the retroreflector geometry and (ii) reflecting radar waves transmitted from a radar device of another vehicle.

When an object detected by a sensor (20L, 20R) is not an unnecessary object and the object's collision probability index satisfies the predetermined condition, a pre-collision control ECU 10 performs a pre-collision control to prepare for a collision between an own vehicle and this object. The pre-collision control ECU determines that the object is the unnecessary object, when an initially detected location which is a location of the object in relation to the own vehicle when the sensor initially detected the object is in an unnecessary object area NA, and a velocity index value which represents a degree of a velocity change of an initial detected object whose the initially detected location is in the unnecessary object area does not fall within a predetermined range.

A method for customer service includes: determining whether a user terminal is inside a vehicle, the vehicle being associated with the user terminal; in response to the user terminal being determined to be inside the vehicle, obtaining a first detection signal of a sensor of the user terminal; in response to the first detection signal satisfying a pre-determined condition, generating an event identifier indicating an occurrence of a collision event, the pre-determined condition being associated with change characteristics of a detection signal in a pre-determined vehicle collision process; obtaining location information of at least one of the user terminal or the vehicle; and transmitting the event identifier and the location information to a customer service device for the customer device to initiate a call to the user terminal in response to receiving the event identifier to confirm a connection status of the user terminal.

A method for controlling an actuatable safety device for protecting an occupant of a vehicle includes sensing a left upfront vehicle acceleration via a left upfront sensor, sensing a middle upfront vehicle acceleration via a middle upfront sensor, and sensing a right upfront vehicle acceleration via a right upfront sensor. The method also includes sensing a central vehicle acceleration via a central airbag control unit. The method further includes determining the occurrence of a vehicle crash event in response to determining that each of the left, middle, and right upfront vehicle accelerations exceeds a predetermined magnitude and is phase shifted from the central vehicle acceleration.

A method for identifying the type and/or the severity of a collision of a vehicle of a first mass with a collision object of a second mass in an early phase to trigger safety measures, including: detecting surroundings data of the vehicle; identifying the collision object from the surroundings data; extracting a reference feature, not lying in a direct collision area, of the collision object; repeated successive ascertainment of an instantaneous speed of the vehicle and determining a change of the speed of the vehicle; repeated successive determination of an instantaneous relative speed between the vehicle and the reference feature and determining a change of the speed of the collision object; estimating a mass ratio, effective during the collision, between the mass of the vehicle and the mass of the collision object from the ascertained changes of the speeds of the vehicle and of the collision object.

An airbag device for a front passenger seat includes a front passenger seat airbag main body, a center airbag portion, an actuator and a control section. The actuator is configured to switch a strap between a first state and a second state. In the first state, the center airbag portion is retained in a folded state. In the second state, the other end portion of the strap is released and the center airbag portion is allowed to inflate and expand. The control section sets the actuator to the first state when there is a full overlap frontal collision, and sets the actuator to the second state when there is a collision that is any of an oblique collision against a driver seat side of a vehicle front portion or a small overlap collision.
