VEHICLE CONTROL APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240190429 titled 'VEHICLE CONTROL APPARATUS
The vehicle control apparatus described in the patent application consists of a meter display ECU and a vehicle speed control ECU. The meter display ECU is responsible for acquiring the GNSS speed of the host vehicle, calculating the gain error of the detected vehicle speed, and determining a meter display speed based on the detected vehicle speed, gain error, and offset value. The offset value is calculated to ensure that the meter display speed is equal to or higher than both the detected vehicle speed and the GNSS speed, based on past gain error calculations. The vehicle speed control ECU utilizes the gain error and offset value obtained from the meter display ECU, along with the detected vehicle speed from the vehicle speed sensor, to calculate the meter display speed.
- Key Features and Innovation:
- Acquisition of GNSS speed for accurate calculations - Calculation of gain error to determine meter display speed - Offset value calculation to ensure accurate meter display speed - Utilization of past gain error calculations for optimization
- Potential Applications:
- Automotive industry for vehicle speed control systems - GPS navigation systems for accurate speed display - Fleet management for monitoring vehicle speeds
- Problems Solved:
- Ensures accurate meter display speed - Optimizes vehicle speed control - Improves overall vehicle performance and safety
- Benefits:
