Abstract
An apparatus for waking up users of a CAN bus system, wherein a sensing element, in particular a counter, is provided which senses at least one predefined signal property of the signals transmitted on the bus system and initiates the further wakeup operation when a predefined number is reached with reference to the signal property, the data stream of the CAN bus itself being used as a clock for detecting the signal property.
Claims15
An apparatus for waking up users of a CAN bus system, comprising:
- a sensing element configured to sense at least one predefined signal property of a signal transmitted on the bus system and to initiate a further wakeup operation when a predefined number is reached with reference to the signal property;
- wherein a data stream of the CAN bus itself is used as a clock cycle for detecting the at least one predefined signal property, and wherein the at least one predefined signal property is a specified number of edges in at least one of an arbitration field and a control field of a CAN message.
A method for waking up users of a CAN bus system, comprising:
- sensing at least one predefined signal property of a signal transmitted on the bus system;
- and
- initializing a further wakeup operation when a predefined number is reached with reference to the signal property;
- wherein a data stream of the CAN bus itself is used as a clock cycle for detecting the at least one predefined signal property, and wherein the at least one predefined signal property is a specified number of edges in at least one of an arbitration field and a control field of a CAN message.

A user of a CAN bus system, comprising:
- an apparatus for waking up users of the CAN bus system, the apparatus including a sensing element configured to sense at least one predefined signal property of a signal transmitted on the bus system and to initiate a further wakeup operation when a predefined number is reached with reference to the signal property, wherein a data stream of the CAN bus itself is used as a clock cycle for detecting the at least one predefined signal property, and wherein the at least one predefined signal property is a specified number of edges in at least one of an arbitration field and a control field of a CAN message.
