First Claim
Patent Images
1. An apparatus, comprising:
- a vehicle controller to;
control a motor operatively coupled to a suspension system to raise or lower a vehicle;
determine a first parameter of the motor while controlling the motor to change a ride height of the vehicle when the vehicle is unloaded;
determine a second parameter of the motor while controlling the motor to change the ride height of the vehicle when the vehicle is at least partially loaded; and
calculate a weight of the vehicle based on the first and second parameters of the motor.

Abstract
Methods and apparatus to determine vehicle weight are disclosed. An example apparatus includes a vehicle controller configured to control a motor operatively coupled to a suspension system to raise or lower a vehicle. The vehicle controller is to also determine a first parameter of the motor while controlling the motor to raise or lower the vehicle when the vehicle is unloaded. The vehicle controller is to also determine a second parameter of the motor while controlling the motor to raise or lower the vehicle when the vehicle is at least partially loaded. The vehicle controller is to also calculate a weight of the vehicle based on the first and second parameters of the motor.

12. A vehicle, comprising:
-
a suspension system; and a controller to; control, via a motor, the suspension system to adjust a ride height of the vehicle; perform a comparison of first and second parameters of the motor, the first parameter based on operating the motor to adjust the ride height of the vehicle when the vehicle is unloaded, the second parameter based on operating the motor to adjust the ride height of the vehicle when the vehicle is at least partially loaded; and calculate a weight of the vehicle based on the comparison. - View Dependent Claims (13, 14, 15, 16)
