Abstract:
The invention relates to a monitoring system for a vehicle. In a parked state of the vehicle, the control unit of the vehicle is deactivated, and the signals of some of the sensors of the vehicle are detected and evaluated by way of a separate detecting unit. If, based on the sensor signals evaluated in this way, a defined event is detected, the previously deactivated control unit can be activated. Thus, the operating time of the control unit is minimized over the total life span of the vehicle.
Abstract:
Die vorliegende Erfindung schafft eine Überwachungsvorrichtung für ein Fahrzeug. Im abgestellten Zustand des Fahrzeugs wird dabei die Steuereinrichtung des Fahrzeugs deaktiviert und die Signale einiger Sensoren des Fahrzeugs über eine separate Detektoreinrichtung erfasst und ausgewertet. Wird basierend auf den so ausgewerteten Sensorsignalen ein vorbestimmtes Ereignis detektiert, so kann die zuvor deaktivierte Steuereinrichtung aktiviert werden. Somit wird die Betriebszeit der Steuereinrichtung über die gesamte Lebensdauer des Fahrzeugs minimiert.

A system adapted to determine a projected range of a vehicle is described. The system includes: a storage element adapted to store a set of parameters associated with a vehicle; a map evaluation element adapted to retrieve information regarding a geographic area associated with a position of the vehicle; and a processing element adapted to determine the projected range of the vehicle based at least partly on the set of parameters and the retrieved information. An automated method of projecting a range of a vehicle includes: generating a set of range projection links; generating a monochrome bitmap based at least partly on the set of range projection links; rendering the set of range projection links within the monochrome bitmap; and tracing the rendered links to generate a polygon outline of the range of the vehicle. An automated method of caching map data for vehicle range projection is described.

Abstract:
Automated charging systems for vehicles having rechargeable batteries are in common use today. Such systems typically have exposed contacts or the need for additional circuitry to move the contacts. The subject system includes circuitry which allows the charge receiving member (130) to be only connected to the battery (110) during charging. The charging system (100) produces a charging signal in response to a low battery. A microprocessor (240) receives the charging signal and responsively produces a 'pulse' signal. A second transistor switch (345) receives the 'pulse' signal and responsively energizes a charging contactor coil (305). In response to the charging contactor coil being energized, contacts (200a, 200b, 300a, 300b) controllably block power from the battery (110) to the motor (115) and pass power from the receiving member (130) to the battery (110).
