Abstract  Determining relative vehicle positioning for vehicle safety warning services requires high level of accuracy. Positioning based on general satellite information has a large margin of error due to cost constraints. This paper proposes a method to determine relative vehicle position for vehicle safety warning, based on conditional extremum and relative vehicle history positioning. Special attention is paid to improve not only the computational efficiency but also the accuracy of determining the relative position of two vehicles or a vehicle and reference frame. Field test results demonstrate the significance of improved accuracy in determining relative vehicle position. Theoretical analysis and realistic systematic tests provide useful insights into potential applications in safety warning.
