About VSS

The Vehicle Signal Specification (VSS) is an initiative by COVESA to define a syntax and a catalog for vehicle signals. The source code and releases can be found in the VSS github repository.

Supported datatypes

The following is a list of VSS supported built-in datatypes:

Name Type Min Max
uint8 unsigned 8-bit integer 0 255
int8 signed 8-bit integer -128 127
uint16 unsigned 16-bit integer 0 65535
int16 signed 16-bit integer -32768 32767
uint32 unsigned 32-bit integer 0 4294967295
int32 signed 32-bit integer -2147483648 2147483647
uint64 unsigned 64-bit integer 0 2^64 - 1
int64 signed 64-bit integer -2^63 2^63 - 1
boolean boolean value 0/false 1/true
float floating point number -3.4e -38 3.4e 38
double double precision floating point number -1.7e -300 1.7e 300
string character string n/a n/a

Min, max and default values defined in a Vehicle Signal Specification must be in the supported range of the data type.
