-- Specification of CDD Data Elements:
------------------------------------------
* The following values are specified:
* - `accelerate` if the acceleration is positive.
* - `decelerate` if the acceleration is negative.
* @category: Kinematics information
* Revision: Created in V2.1.1
*/
AccelerationChange::= ENUMERATED { accelerate, decelerate } -- tbd add values and/or extension?
* This DE reprents the absolute accuracy of a reported vehicle acceleration value with a confidence level of 95%.
* - `1` if the acceleration accuracy is equal to or less than 0,1 m/s2.
* - `n (n > 1 and n < 101)` if the acceleration accuracy is equal to or less than n x 0,1 m/s2, and more than (n-1) x 0,1 m/s2.
* - `101` if the acceleration accuracy is out of range i.e. greater than 10 m/s2.
* - `102` if the data is unavailable.
* @note: The fact that an acceleration value is received with confidence set to 'unavailable(102)' can be caused by several reasons, such as:
* - the sensor cannot deliver the accuracy at the defined confidence level because it is a low-end sensor,
* - the sensor cannot calculate the accuracy due to lack of variables, or
* - there has been a vehicle bus (e.g. CAN bus) error.
* In all 3 cases above, the reported acceleration value may be valid and used by the application.
*
* If an acceleration value is received and its confidence is set to `outOfRange(101)`, it means that the value is not valid and therefore cannot be trusted. Such value is not useful for the application.
AccelerationConfidence ::= INTEGER {

* This DE indicates the current controlling mechanism for longitudinal movement of the vehicle.
* The data may be provided via the in-vehicle network. It indicates whether a specific in-vehicle
* acceleration control system is engaged or not. Currently, this DE includes the information of the
* vehicle brake pedal, gas pedal, emergency brake system, collision warning system, adaptive cruise
* control system, cruise control system and speed limiter system.
* The corresponding bit shall be set to 1 under the following conditions:
* - 0 `brakePedalEngaged` : Driver is stepping on the brake pedal,
* - 1 `gasPedalEngaged` : Driver is stepping on the gas pedal,
* - 2 `emergencyBrakeEngaged` : emergency brake system is engaged,
* - 3 `collisionWarningEngaged`: collision warning system is engaged,
* - 4 `accEngaged` : ACC is engaged,
* - 5 `cruiseControlEngaged` : cruise control is engaged,
* - 6 `speedLimiterEngaged` : speed limiter is engaged.
* - 7 : reserved for future use
* Otherwise (for example when the corresponding system is not available due to non equipped system
* or information is unavailable), the corresponding bit shall be set to _0_.
* @note: The system engagement condition is OEM specific and therefore out of scope of the present document.
