Abstract:
Fuel or additive pump controller is integrated to a fuel system control unit (FSCU), and communicates with an engine control unit (ECU) and/or crash sensors through communication means. The controller comprises means for generating a pump control signal. Said means use data on crash occurrence from the ECU or from said crash sensors for turning off the pump or limiting the pump speed in case of crash.
Abstract:
The method of controlling fuel supply comprises the steps of detecting a value related to velocity of a vehicle along a first path and detecting a value related to velocity along a second path transverse to the first path. The detected values are then combined and compared to a threshold. The fuel supply is then controlled based on the comparison of the combined values with the threshold. Using this method, a fuel safety system comprises a fuel system of a vehicle, a fuel cutoff switch controlling the transmission of fuel through the fuel system, a sensor detecting a value related to velocity of the vehicle along the first path, and a sensor detecting a value related to velocity of the vehicle along a second path transverse to the first path. A control unit combines the detected values and activates the fuel cutoff switch based on the comparison.
Abstract:
The invention relates to a method which is used to detect tilt in a motor vehicle around an axis oriented in the longitudinal direction of said vehicle. In order to achieve this, a variable describing the speed of at least one wheel and at least one other variable representing the transversal dynamic of said motor vehicle are determined. Braking and/or driving torque is momentarily produced or modified according to one of the transversal dynamic variables. Whilst the braking and/or driving torque is momentarily produced and/or modified and/or after production and/or modification thereof, a quantitative variable describing the speed of at least one wheel is determined according to the variable describing the speed of said wheel. Tilting in the motor vehicle around a vehicle axis oriented in the longitudinal direction thereof is determined on the basis of said variable.
Abstract:
The aim of the invention is to provide a means for determining the inertial position of a vehicle whilst excluding interference caused by dynamic vehicle movements as completely as possible. To this end, the accelerations (az, ay, ax) of the vehicle in the direction of its vertical axis (z) and in the direction of its lateral axis (y) and/or its longitudinal axis (x) are measured and the position angle ( phi x) of the vehicle (FZ) in relation to its longitudinal axis (x) and/or the position angle ( phi y) in relation to its lateral axis (y) is determined from the acceleration (ay, ax) in the direction of the lateral axis (y) or the longitudinal axis (x) and the acceleration (az) in the direction of the vertical axis (z), according to the relations (1): phi x1 = arcsin (ay/g), phi y1 = arcsin (ax/g) and (2): phi x2 = arccos (az/g), phi y2 = arccos (az/g). The smaller of the two angles phi x1 and phi x2 or phi y1 and phi y2 is taken as the inertial position angle.

The second integrated circuit-based electronic controller is configured to determine an unintended acceleration event in response to the acceleration and braking requests, and the acceleration outputs of the three-axis accelerometer.

An improved distributed information sharing system (DISS) and methods for an autonomous vehicle, the DISS programmed and configured to receive information from a plurality of distributed sensors; determine the existence of an incident, vehicles, passengers, pedestrians, animals and objects involved in the incident, a nature of the injuries and damages from the incident; determine if the autonomous vehicle can be safely moved autonomously from a location where the incident occurred to a second location; contact an emergency responder when the vehicle cannot be safely moved autonomously; receive a request to transfer control of the vehicle from an emergency responder user device; and in response, transfer control of the automated vehicle to a trusted emergency responder without requiring approval from an owner of the vehicle using encryption and handshake techniques; and notify an owner or interested party of the vehicle of the incident.
Abstract:
The invention relates to a multifunctional, flameproofed transmission control module [10] adapted for automatically altering transmission performance based on an alert received from a Proximity Detection System (PDS) [12]. The transmission control module [10] comprises a Proximity Detection Interface (PDI) [14] which is electronically linked to a PDS [12] and which is adapted to reduce transmission performance and vehicle speed the moment an obstacle is detected within a detection zone, and to allow an increase in transmission performance and vehicle speed the moment an obstacle is no longer detected within a detection zone.
Abstract:
A vehicle safety rollover device utilizing a circular arc level for detecting vehicle rollover is disclosed. Upon detection, the device automatically shuts-off power to an ignition system and notifies for shut-down of the electrical system of the vehicle. The circular arc level is capable of measuring gravitational norm deviation while remaining impervious to the effects of acceleration, deceleration, impact, and centripetal forces.
