A grade and acceleration sensor having a weight, a first sensor for measuring a first parameter of the weight due at least to the force of gravity to generate a first signal, a second sensor for measuring a second parameter of the weight due to both the force of gravity and the acceleration of the vehicle on which the sensor is mounted to generate a second signal, a grade angle generator generating the grade angle theta in response to the first and second signal, and an acceleration generation generating a signal having a value corresponding to the acceleration of the vehicle in response to the first and second signals. In a first embodiment, the weight is a bob of a pendulum, the first parameter is a displacement angle of the bob due to acceleration and gravity and the second parameter is the force on the arm of the bob due to gravity and acceleration. In a second embodiment, the first parameter is force generated by a weight due to gravity along a first axis and the second parameter is the force generated by the weight due to acceleration and gravity along a second axis normal to the first axis.
