Abstract
The present invention provides methods and systems for determining the weight of a vehicle. Exemplary methods include the steps of: determining with one or more on-board sensors, a sensor output voltage; providing the sensor output voltage information to a processing unit to determine the weight of the vehicle; and displaying the weight of the vehicle on a visual display unit.
Claims20
A method of determining a weight of a vehicle, the method comprising the steps of:
- a) determining with one or more on-board sensors, a sensor output voltage, wherein the one or more on-board sensors are connected directly to vehicle suspension components and wherein a position of the suspension components is directly related to a load on an axle to which a relevant sensor is connected and wherein the one or more on-board sensors are connected to a vehicle stabilizer bar;
- b) providing sensor output voltage information corresponding to the sensor output voltage to a processing unit, movement of a stabilizer bar results in one or more of the on-board sensors transmitting sensor output voltage information to the processing unit and the processing unit analysing the sensor output voltage information to determine the weight of the vehicle by converting the sensor output voltage information received form one or more sensor using a mathematical algorithm;
- and
- c) displaying the weight of the vehicle on a visual display unit.
An in-vehicle weighing system comprising:
- a processing unit adapted to determine a weight of a vehicle;
- one or more on-board sensors functionally connected to the processing unit wherein the one or more on-board sensors are connected directly to vehicle suspension components and wherein a position of the suspension components is directly related to a load on an axle to which a relevant sensor is connected and wherein one or more of the on-board sensors are connected to a vehicle stabilizer bar, movement of the stabilizer bar results in one or more of the on-board sensors transmitting sensor output voltage information to the processing unit;
- and
- a visual display unit to display the weight of the vehicle thereon,
- wherein the one or more on-board sensors provide sensor output voltage information to the processing unit to determine the weight of the vehicle by converting the sensor output voltage information received from one or more sensor using a mathematical algorithm.
A method of modifying a vehicle to be able to determine a weight of the vehicle, the method comprising the steps of:
- a) mounting a plurality of on-board sensors on suspension components of the vehicle, wherein the on-board sensors are adapted to transmit sensor output voltage information, the one or more on-board sensors are connected directly to vehicle suspension components, and wherein a position of the suspension components is directly related to a load on an axle to which a relevant sensor is connected and wherein one or more of the on-board sensors are connected to a vehicle stabilizer bar;
- and
- b) providing a processing unit in the vehicle, wherein the processing unit is functionally connected to the on-board sensors and adapted to receive and analyse sensor output voltage information therefrom whereby movement of the stabilizer bar results in one or more of the on-board sensors transmitting sensor output voltage information to the processing unit and said processing unit analysing the sensor output voltage information and determine the weight of the vehicle by converting the sensor output voltage information received from one or more sensor using a mathematical algorithm.
