Abstract
In a method and apparatus for collision avoidance or collision mitigation for a vehicle, an existing driving space between the vehicle and a potential collision object is detected. A first warning function and/or an information function is activated when a first threshold value is reached. A system intervention with autonomous partial braking combined with at least one further safety measure is activated when a second threshold value is reached.
Claims14
A method for operating a collision avoidance or mitigation system of a vehicle, said method comprising:
- detecting an existing driving space between the vehicle and a potential collision object;
- activating at least one of a first warning function and an information function when a first threshold value is reached;
- and
- activating a system intervention with autonomous partial braking combined with at least one further safety measure when a second threshold value is reached;
- wherein, said partial braking is a braking that is limited such that a resulting deceleration does not exceed a predetermined maximum value,
- wherein said partial braking is limited to a deceleration value that is less than a deceleration that is necessary to avoid a collision.
A method for operating a collision avoidance or mitigation system of a vehicle, said method comprising:
- detecting an existing driving space between the vehicle and a potential collision object;
- activating at least one of a first warning function and an information function when a first threshold value is reached;
- and
- activating a system intervention with autonomous partial braking combined with at least one further safety measure when a second threshold value is reached;
- wherein, said partial braking is a braking that is limited such that a resulting deceleration does not exceed a predetermined maximum value,
- wherein the partial braking is carried out with a braking acceleration which is limited to a maximum of 90% of a deceleration required for collision avoidance,
- wherein the braking acceleration of the partial braking is limited to a maximum limit, which is predetermined dependent upon speed, and
- wherein at low driving speeds, a higher limit is set for the braking acceleration of the partial braking than at higher driving speeds.
A collision avoidance or collision mitigation system for a vehicle comprising:
- means for detecting an existing driving space between the vehicle and a potential collision object;
- means for activating at least one of a first warning function and an information function when a first threshold value is reached;
- and
- means for activating a system intervention with autonomous partial braking combined with at least one further safety measure when a second threshold value that is less than said first threshold value is reached;
- wherein, said partial braking is a braking that is limited such that a resulting deceleration does not exceed a predetermined maximum value,
- wherein said partial braking is limited to a deceleration value that is less than a deceleration that is necessary to avoid a collision.
