Abstract

An electronic stability control indication system including a bar-graph-type display, a processor, and a memory. The memory stores instructions that, when executed by the processor, control the operation of the electronic stability control indication system. The system receives a first signal from a yaw rate sensor indicative of an actual yaw rate of the vehicle. The system then determines a target yaw rate and a threshold difference for the vehicle. If the difference between the actual yaw rate and the target yaw rate exceeds the difference threshold, an electronic stability control system is activated. The system also provides a visual representation of the difference between the actual yaw rate and the target yaw ratio relative to the threshold difference on the bar-graph-type display.

Claims

1. A vehicle intervention indication system, the system comprising:

a display;

a processor; and

a memory storing instructions that, when executed by the processor, cause the vehicle intervention indication system to

receive a first signal indicative of a value sensed by a first vehicle sensor,

determine a target vehicle performance value,

calculate a difference between the target vehicle performance value and the determined vehicle performance value,

compare the difference between the target vehicle performance value and the determined vehicle performance value to an intervention threshold,

apply intervening corrective measures to at least one vehicle system when the difference between the target vehicle performance value and the determined vehicle performance value exceeds the intervention threshold, and

provide on the display an indication of a ratio of the difference between the target vehicle performance value and the determined vehicle performance value relative to the intervention threshold.

2. The vehicle intervention indication system of claim 1, wherein the target vehicle performance value is a target yaw rate and the determined vehicle performance value is an actual yaw rate.

3. The vehicle intervention indication system of claim 1, wherein the display includes a linear display element, and wherein the indication provided on the display includes a visual representation of the ratio on the linear display element.

4. The vehicle intervention indication system of claim 3, wherein the linear display element includes a digital bar graph where one end-point of the digital bar graph represents a condition where the determined vehicle performance value is equal to the target vehicle performance value and an opposite end-point of the digital bar graph represents a condition where the difference between the determined vehicle performance value and the target vehicle performance value exceeds the intervention threshold.

5. The vehicle intervention indication system of claim 3, wherein the linear display element includes a digital bar graph where one end-point of the digital bar graph represents a condition where the determined vehicle condition value exceeds the target vehicle condition value by at least the intervention threshold, an opposite end-point of the digital bar graph represents a condition where the determined vehicle condition value is less than the target vehicle condition value by at least the intervention threshold, and a middle point of the digital bar graph represents a condition where the determined vehicle condition value is equal to the target vehicle condition value.

6. The vehicle intervention indication system of claim 1, wherein the display includes a numeric display element, and wherein the indication provided on the display includes a numeric representation of the ratio as a percentage.

7. The vehicle intervention indication system of claim 1, wherein the first vehicle sensor includes a yaw rate sensor.

8. The vehicle intervention indication system of claim 1, wherein the instructions, when executed by the processor, further cause the vehicle intervention indication system to receive a second signal indicative of a value sensed by the second vehicle sensor, and wherein the vehicle performance value is determined based at least in part on the first signal and the second signal.

9. An electronic stability control indication system, the system comprising:

a bar-graph-type display;

a processor; and

a memory storing instructions that, when executed by the processor, cause the vehicle intervention indication system to

receive a first signal from a yaw rate sensor indicative of an actual yaw rate of the vehicle;

determine a target yaw rate for the vehicle;

determine a threshold difference for the vehicle;

determine a difference between the actual yaw rate and the target yaw rate;

activate an electronic stability control system when the difference between the actual yaw rate and the target yaw rate exceeds the threshold difference;

calculate a ratio of the difference between the target yaw rate and the actual yaw rate relative to a threshold difference;

provide an output on the bar-graph-type display, the output including a visual representation of the ratio of the difference between the actual yaw rate and the target yaw rate relative to the threshold difference.

10. The electronic stability control indication system of claim 9, wherein, when the actual yaw rate is equal to the target yaw rate, the visual representation on the bar-graph-type display includes a full bar.

11. The electronic stability control indication system of claim 10, wherein, when the difference between the actual yaw rate and the target yaw rate exceeds the threshold difference, the visual representation on the bar-graph-type display includes an empty bar.

12. The electronic stability control indication system of claim 9, wherein, when the difference between the actual yaw rate and the target yaw rate exceeds the threshold difference, the visual representation on the bar-graph-type display includes a full bar.

13. The electronic stability control indication system of claim 12, wherein when the actual yaw rate is equal to the target yaw rate, the visual representation on the bar-graph-type display includes an empty bar.
