The　paper　firstly　analyzed　the　characteristic　of　vehicle　road　way　test　and　the　structure　of　the　test　system,　and　then　brought　up　the　development　tendency　of　high　reliability,　high　integration,　synchronizing　data　acquisition,　CAN　communication　interface,　and　so　on.　Thirdly,　three　key　technologies　were　reviewed　concretely　in　light　of　the　industrialization　requirement　of　vehicle　dynamic　stability　control　system,　i.e.　DSC,　which　include　measurement　method　of　the　path　and　attitude　of　vehicle,　the　wheel　force　measurement　technology　and　the　steering　input　control　method.　The　main　stream　of　measurement　technology　for　vehicle　road　way　test　in　future　may　be　the　GPS　only　based　measurement　method　of　the　path　and　attitude　of　vehicle,　wheel　force　transducer　based　wheel　force　measurement　method,　the　integration　measurement　of　GPS　devices　and　steer　robot　for　the　precisely　steer　control　and　path　following　road　way　tests.
