1. A vehicle system comprising:
- a first sensor configured to output a child restraint signal indicating a presence of a child restraint system;
a second sensor configured to output a belt tension signal representing a tension associated with a seat belt; and
a processing device programmed to distinguish between a child seat and a booster seat based on the child restraint signal and the belt tension signal.

Abstract
A vehicle system includes at least two sensors. A first sensor is configured to output a child restraint signal indicating a presence of a child restraint system. A second sensor is configured to output a belt tension signal representing a tension associated with a seat belt. A processing device is programmed to determine whether the child restraint system includes a child seat or a booster seat based on the child restraint signal and the belt tension signal.
