Abstract
An apparatus for estimating vehicle weight using a vehicle height adjusting device is provided. The apparatus includes a vehicle height adjusting device that raises or lowers four positions of front left (FL) and right (FR) sides and rear left (RL) and right (RR) sides of a vehicle body, respectively. A vehicle height controller operates the vehicle height adjusting device to raise or lower the FL and FR sides and the RL and RR sides of the vehicle body. A weight estimating unit measures time required for raising or lowering the vehicle body or operating speed of the vehicle body and calculates an expected vehicle weight value by comparing the time required or the operating speed with a preset reference data.
Claims16
An apparatus for estimating vehicle weight by using a vehicle height adjusting device, comprising:
- a vehicle height adjusting device configured to raise and lower four positions of front left (FL) and right (FR) sides and rear left (RL) and right (RR) sides of a vehicle body, respectively;
- a vehicle height controller configured to operate the vehicle height adjusting device to raise or lower the FL and FR sides and the RL and RR sides of the vehicle body;
- and
- a weight estimating unit configured to:
- measure time required for raising the vehicle body or operating speed of raising the vehicle body and time required for lowering the vehicle body or operating speed of lowering the vehicle body;
- compare the time required for raising the vehicle body or the operating speed of raising the vehicle body with a preset reference data to calculate a first expected vehicle weight value according to a presets calculation criterion;
- compare the time required for lowering the vehicle body or the operating speed of lowering the vehicle body with the preset reference data to calculate a second expected vehicle weight value according to the preset calculation criterion;
- and
- calculate a final expected vehicle weight value by applying preset weights to the first expected vehicle weight value and the second expected vehicle weight value, respectively.
A method of estimating vehicle weight by using a vehicle height adjusting device, comprising:
- raising or lowering by a controller, front left (FL) and right (FR) sides and rear left (RL) and right (RR) sides of a vehicle body by operating the vehicle height adjusting device;
- and
- calculating, by the controller, an expected vehicle weight value by measuring time required for raising or lowering the vehicle body or operating speed of raising or lowering the vehicle body, and by comparing the time required or the operating speed with preset reference data;
- wherein the calculating of the expected vehicle weight value includes:
- measuring, by the controller, the time required for raising the vehicle body or the operating speed of raising the vehicle body and the time required for lowering the vehicle body of the operating speed of lowering the vehicle body;
- calculating, by the controller, a first expected vehicle weight value according to a preset calculation criterion by comparing the time required for raising the vehicle body or the operating speed with the preset reference data;
- and
- calculating, by the controller, a second expected vehicle weight value according to the preset calculation criterion by comparing the time required for lowering the vehicle body or the operating speed with the preset reference data;
- and
- wherein preset weights are applied to the first expected vehicle weight value and the second expected vehicle weight value, respectively to calculate a final expected vehicle weight value.
